Laser speed measurement, a precise optical technique, utilizes laser light to accurately determine the rotational speed of objects. This non-contact method employs a laser source to emit a beam at the rotating object, which reflects back to a photodetector. The time of flight of the reflected beam is precisely measured, and the rotational speed is computed based on the known distance between the laser and the object. This technique offers high accuracy, wide measurement range, and the ability to measure speeds in hazardous or inaccessible environments, making it invaluable in various industries such as manufacturing, automotive, and aerospace.
