[QUOTE="greybeard, post: 1648757, member: 18945"] The differences between the types. Night vision just gathers natural or existing light (from stars and moon), amplifies that light to allow you to see a bit better. Think the old Starlight scope from the Vietnam era war movies. I've used them (a bulky monocle) and found them frustrating in anything but a clear crisp night, with low humidity. mejor que nada...better than nothing. It was basically a spotting scope. Cheap thermal simply measures the differences between a target and the air immediately surrounding the object and displays 'an outline'. Better thermal measures better/tighter and uses the light gathering capability of night vision combined with thermal to show the actual object. The thermal scope is actually looking at IR signatures, but how it is displayed to the viewer is the difference between a thermal scope and a better IR scope. IR picks up light in a different wavelength. A good thermal/IR scope or camera shows the shape very clearly. [/QUOTE]
