A Look at Night Vision Goggles

There are many reasons that someone might want to use night vision goggles. They are great for hunting, for example, and they can have law enforcement or security uses. They’re also a lot of fun just to play with if you like camping or exploring.

Night vision devices, in their most basic form, were first created for actual field use during World War II, and they became more commonplace during the Vietnam War.

The first practical devices were used by the Germans in 1939 – they were based on devices that AEG developed a few years previously. The first infrared night-vision products became popular in 1943, when telescopic range fingers, and Nacht Jager night-vision devices were mounted on the Panther line of tanks. From there, other forces involved in the war started working on night vision devices too. The Germans eventually deployed the Vampir – a man-portable version of the night vision technology which was suitable for use with the Sturmgewehr 44 assault rifle.

Over time, the technology used in night vision goggles has improved a lot. Third generation systems were based on MCP which was also used in Gen II, but the photocathode is made from gallium arsenide, which helps to improve image resolution. The MCP has an ion barrier film, which helps to mak the tube last longer. There is one downside to the ion barrier, though – it allows fewer electrons through it, which means that there is a bigger halo effect around light sources and bright spots in the field of view. However, light amplification is improved significantly.

Photons from a low quality light source enter the objective lens in the goggles and then strike the photocathode. The photcathode will release electrons, which are accelerated, and this allows the higher-voltage microchannel plate to amplify the light. Electrons are drawn to a higher-voltage screen of phosphor, and when they strike the phosphor this causes it to release photons, which can be sen through the eyepiece.

The US Arm’s Night Vision Electronic Sensors Directorate includes naming conventions for different types of night vision technology, according to their ‘generation’. The current high performance goggles are GEN-III OMNI-VI-VII, but the Army has not given permission for any components to use the name ‘GEN-IV’.

There are a few key differences between GEN-III and the OMNI-V-VII improvements – one of the main ones being the presence of a system which regulates the voltage sent to the photocathode, allowing the unit to adapt to changes in light conditions pretty quickly.

In the consumer market, this system is classed as being Generation 4, but the military thinks of it as third generation, because it still uses Autogated tubes. Autogating power supplies can actually be added to any of the previous generations of night vision goggles.

The modern ATG function is designed to allow for better resolution and contrast even in rapidly changing conditions. ATG is an interesting feature which constantly operates, and which will help to protect the user from potentially being blinded if they go through a rapid day-night-day transition, or if a dark room is suddenly illuminated. ATG can also help to reduce the temporary blindness that you might have to worry about in flame bursts, or shootings – which are something that could be a concern in a military or security application.

During the 90s and early 2000s, there were some significant improvements made to the quality and resolution of night vision googles, and today they offer very good clarity, but there are still a lot of things that could be improved with them, and consumer grade units are not quite as good as the military ones.

How To Choose Your Hidden WiFi Cameras

Technology progress has changed our world. As new gadgets are launched, the prices of older ones become accessible to a wide category of people. Almost everybody can afford a smartphone or a tablet computer today. Professional photo cameras have also become less expensive than a decade ago. Video surveillance services have become the norm for all businesses that care about their security. Hidden WiFi cameras are widely available and their prices are decent.

Under these circumstances, there are many people who buy and install hidden cameras in their homes, and then view what happens in those rooms while they are away. These tiny gadgets are priceless, as they can give parents the peace of mind that their children are safe with their nannies. These cameras allow for live remote viewing on both Android and iPhone devices, as well as on desktop computers and laptops. Some of them have the ability of video recording, so they can be used for monitoring purposes by store owners.

When choosing your camera, you need to take into consideration the specific requirements of your project. If you want to check out the behavior of your child’s nanny, you may not need an extremely high-resolution camera. You may not require recording capabilities, either. On the contrary, if you want to find out what your dog does when you are not at home, you may want to have video recording, as you could hit it big online, on YouTube or on Facebook. If you surprise your pet doing some amazing tricks while you are away, you have the chance to use this footage for making videos with high viral potential. In such cases, you have to make sure your WiFi camera can shoot in HD resolution, as you’ll want users to have a good experience watching your video productions.

When you install such cameras, you need to make sure they are hidden, thus being very difficult to spot by other people. As they are very small, you may be able to hide them inside various toys or décor items in your house. A little creativity would be more than welcome, but you need to be certain the camera is going to fit inside your chosen item.

If you aren’t sure what type of camera you should buy, you can always ask a shop assistant to help you pick the right model. If you intend to purchase your WiFi camera online, you’ll have to perform a close comparison of all the models that are compatible with your viewing device, in order to choose the one that includes all functions you need. Don’t forget to check the size of various cameras, as you need to be able to install them in a way that doesn’t make them visible. If your nanny finds out what you’ve done, she may get very upset and quit her job, so don’t risk to get exposed. If you make the right choice, you’re going to have a seamless monitoring experience, while keeping it totally private.

Getting Started With Stargazing: Astronomy Binoculars

Stargazing is one of the world’s oldest hobbies; it surely predates the dawn of recorded history. Stargazing is the original pastime that led to the science of astronomy, a field of study that today encompasses trying to understand everything you see in the sky and, indeed, the origins of the universe itself. Looking up at the stars above us is a passion for many people and even a profession for a lucky few. Although uncovering the most subtle secrets of the heavens and getting the best views of the stars requires a lot of very expensive equipment, you can still see some amazing sights without investing a lot of money in specialized gear. Even a humble set of astronomy binoculars can dramatically increase the number of sights within your reach. Here’s a basic introduction to amateur astronomy.

Learning About The Sky

While direct observation of all the wonders above you is the primary goal of stargazing, it certainly helps to know what you’re looking at. Familiarizing yourself with the basic structures of the sky (like the constellations) will give you a deeper appreciation for the things you see and make your experiences more rewarding.

Your local library is an excellent place to start your learning. You’ll find a whole section devoted to astronomy in any decent public library, and reviewing the guides shelved there will give you a terrific foundation for stargazing. In the modern age, of course, online research is an option as well. Learn from those resources that are most convenient and helpful to you personally.

While you should let your own interests dictate where you choose to focus your study time – and your stargazing – one basic subject you’ll want to cover in some depth are the various coordinate systems used to locate stars and other objects in the sky. These may vary from region to region, so you’ll want to take a look at both local and international standards. Mastering coordinate systems will enable you to search out favorite stars or notable events (like meteor showers) with ease.

Equipping Yourself For Your Hobby

Your first instinct might be to start saving up for a telescope as soon as you decide to pursue stargazing in a serious way. While there’s no doubt that telescopes are useful, you needn’t put off the start of your astronomical career until you can afford to buy a good one. A decent set of astronomy binoculars will get you out into the night and scanning the heavens much more quickly. Besides being affordable, binoculars are also especially suited to novice astronomers because they give you a very wide field of view. Don’t forget that binoculars are portable, too; you can take yours anywhere and indulge in stargazing at any time.

Making Astronomy Fun

Amateur astronomy often becomes a matter of seeking out predetermined targets. You want to get a good view of a particular star, and it might feel like a failure if you can’t catch that glimpse. Remember that patience is a key part of this hobby. Sometimes weather conditions or light pollution make it impossible to zero in on your chosen target on a given night. That doesn’t mean you should turn away from all the other wonders of the cosmos above you. Remember that astronomy can and should be a relaxing, restorative pastime. Keep your binoculars moving and remember that there’s always something new and exciting to see in the sky above you.
