What are these telescopes/monocular things actually called ?

I have seen this thing in a lot of movies before. I was watching “The Bourne Ultimatum” yesterday, where Matt Damon uses this mini telescope/monocular kinda thing for spying over.

There are several different devices. Those that contain prisms to erect the image are called, hand held in small sizes, monoculars (in other words, half a binocular), and in larger sizes, spotting scopes. The latter are used on tripods for nature watching and checking targets while shooting. What you are asking about is a specialized version of these called a rangefinder. This has some means of measuring how far away the target is. These use various techniques to actually measure the distance. These include parallax (making two views coincide and measuring using trigonometry), measuring focus change, and bouncing a laser or infrared beam off the object. These are very much more expensive than a standard monocular/spotting scope, and are all called “rangefinders.” Golfers typically use these to estimate the length of a drive.
