Beta LaserMike, Dayton, Ohio, has developed the LaserSpeed™ 9000 non-contact measurement gauge to accurately determine the speed and length of any moving surface or product down to zero speed and even reverse speed.

The LaserMike, designed for use as an add-on for mechanical tachometers, utilizes Laser Doppler Velocimetry technology to improve measurement accuracy, a Bragg Cell to shift frequency and proprietary microelectronics.
