Eyepiece image of a naval rangefinder, showing the displaced image when not yet adjusted for range. The coincidence rangefinder uses a single eyepiece. Light from the target enters the rangefinder through two windows located at either end of the instrument. At either side the incident beam is reflected to the center of the optical bar by a ...
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.
While an early form of mechanical rangekeeper, it does illustrate all the basic principles. [2] The rangekeepers of other nations used similar algorithms for computing gun angles, but often differed dramatically in their operational use. [3] In addition to long range gunnery, the launching of torpedoes also requires a rangekeeping-like function ...
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
The rangekeepers required a large number of electrical signal cables for synchro data transmission links over which they received information from the various sensors (e.g. gun director, pitometer, rangefinder, gyrocompass) and sent commands to the guns.
Soldier observed at 400 m: The stadiametric rangefinder in the bottom-left corner of the PSO-1 telescopic sight reticle can be used to determine the distance from a 1.70-meter (5 ft 7 in) tall person or object from 200 m (bracket number 2 to the right) to 1,000 m (bracket number 10 to the left).
