Night Vision - Gun Detection

Posted by on September 24, 2009 – 8:30 am

Study: gun detection in lowlight conditions using different generations of night vision devices.

One of the biggest concerns of police officers is to know whether the suspect they are dealing with is armed or unarmed. Even during the day it can be hard to detect a gun. And in low-light conditions it can become practically impossible. Knowing whether the suspect is armed or not helps officers to make the right decision and take appropriate actions towards him.

How do night vision devices of different generations help in this situation? We at N-Vision Optics have taken several pictures in different light conditions with 1st, 2nd and 3rd generation devices.

It should be noted, that real life images provided by night vision devices look better than in the pictures, because the camera reduces the quality of the image.

Picture 1 was taken in regular daylight conditions. We used a Bluegun® for this picture as well as all other pictures below. You can see, that when there is no contrast between weapon and clothes (like in this example – black shirt and blue gun), even in daylight it can be hard to get a sight of a gun. With a real gun the results are a little bit different, but similar. The reflecting capacity of the gun depends on its finish. Some guns have more reflective finish than others and those would reflect light better than rubber handle of our Bluegun®. Other guns, that have matted finish, would be harder to see (i.e. the barrel of our gun is really impossible to notice in the pictures below). So the results that you could see on our pictures are somewhat average.
