What are image amplifiers?
Image integrated are devices that increase the ambient light to help vision in low illuminated situations. Image interactions are used in night vision glasses as well as in the number of scientific devices such as microscopes and binoculars. Image interactions work using a photochat to convert the ambient light into electrons and, after being converted back to the photons, intensify the signal. They have been used since World War II and have undergone four generations of technology. It was simply a way to see an infrared spectrum, allowing sniper to see infrared rays that were invisible to their enemies.
The first -generation intense in the Vietnam War was placed and provided a significant improvement compared to zero generation. Although there was still a large amount of surrounding light, so the night without the moon was basically dark, they were able to dramatically intensify this light. Although the first -generation image amplifiers have been an army sinceMore or less abandoned, they are still widely used among amateurs because of their relatively low costs.
The second -generation image of the second -generation image offered a dramatic but short -term lived, advanced in the night vision technology. By introducing new components, second generation amplifiers were able to achieve a completely passive and highly improved night vision. And unlike earlier generations, the new technology was very energy efficient, allowing more than 30 hours of use in a single battery charging.
Soon after the second -generation breakthrough, experiments with new materials for tubes with photocathodes brought a much better form of night vision. Using the Gallium arsenide instead of the S-25 in second-generation intensifying, the third-generation amplifier has achieved much high improvements with more clarity and the ability to use more star light.
intensifies the intensified third generation JSOU widely used by the US and other troops around the world, and some astronomers are also used for activities such as a meteor spot. However, the intensification of the first and second -generation images is still available to buy and are widely used in the consumer population because they are much more accessible than their third generation counterparts.
A handful of manufacturers began to produce what the fourth -generation image amplifiers say. These new amplifiers use basically the same technology as the third generation, with better resolution, less distortion from bright light sources and significantly reduced noise in the image.
It should be noted that image amplifiers are not the same as thermal displayers that can be used in situations without light. Image interactions occupy light from a visible specification and a library around it and intensify it. Heat is much, much lower on the light spectrum and requires a completely different technology.
night vision systems can moveFrom $ 300 to a degree of more than $ 50,000 for top technology.
