What Is Night Vision?

Most of us have seen night vision in use on the movies or on TV. So with night vision technology, it illuminates by using infrared light the human eye cannot see, light from the stars or moon, for instance. But the devices do require light and will not operate in total darkness.These devices are equipped with what is known as an image intensification tube (IIT) or, if the device is digital, then it relies on a charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) and a micro display. The digital night vision is the most advanced type within the group of night vision devices that does not use thermal imaging.Compared with the original generations of night vision, digital devices don’t rely on the traditional image intensifier tube, light is converted to an electronic signal and that’s a difference maker because, now, with the digital devices, you don’t have to worry about damaging the tech in the daytime. Daytime use is completely safe. The other key feature of digital is the images are much sharper and more detailed than traditional night vision.
