Source: Scribbr Understanding Laser Triangulation The Principle of Laser Triangulation Laser triangulation is a method used for distance measurements, commonly employing a laser beam. This technique takes advantage of the laser beam’s ability to travel in a well-collimated form over long distances. In laser triangulation, the laser beam is directed towards a point whose distance […]

Source: Facebook Understanding Laser Rangefinders Understanding Laser Rangefinders How Laser Rangefinders Work Laser rangefinders often utilize the phase shift method to measure distances. A laser beam with modulated optical power is directed towards a target. The reflected light is monitored, showing a power modulation with the same frequency. By comparing the phase of the modulation

Source: MDPI Understanding Time-of-Flight Measurements Time-of-flight measurements are commonly used for distance measurements, such as in laser rangefinders or scanning laser radars. In this method, a short light pulse is emitted, and the time taken for a reflected portion of the pulse to return is measured. The distance is then calculated based on the round-trip

Dioptric power is the inverse of the effective focal length of an optical element. It is measured in diopters (dpt) or m-1. This specification is commonly used for prescription glasses, while focal length is more typical for standard lenses
