Rangefinder Camera Mechanism. Some cameras do not have a beam splitter; these cameras instead have a separate viewfinder.The first rangefinders, sometimes called "telemeters", appeared in the twentieth century; the first rangefinder camera to be marketed was the 3A Kodak Autographic Special of 1916; the rangefinder was coupled.
Consider Figure 5 for example. In this case the gun angle as a function of target's range and the target's relative elevation is represented by the thickness of the cam at a given axial distance and angle. A gun direction officer would input the target range and relative elevation using dials. The pin height then represents the required gun angle.
A stereoscopic rangefinder or stereoscopic telemeter [1] is an optical device that measures distance from the observer to a target, using the observer's capability of binocular vision. It looks similar to a coincidence rangefinder, which uses different principles and has only one eyepiece. German instruments tended to use the stereoscopic ...
Coincidence rangefinders work through the principle of triangulation. In the pictured example, triangulation can be used to determine the range of the ship 𝑑.The position of the lenses A and B are known, and the angle of the lenses α and/or β is set by the operator so that both are aimed at the target.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
scope (equipment) – A sight housing that resembles a scope, containing one or more pins used to align the bow with the target. Some housings, mainly used in target archery and often sold separately from the rest of the sight, can accept lenses (see clarifier). self bow (equipment) – A bow made from a single piece of material (normally wood)
