A Laser Doppler Sensor is a device that uses laser light to measure the velocity or speed of a moving object. It works by bouncing a beam of laser light off of the moving object and detecting the frequency of the reflected light, which changes depending on the speed of the object. Laser Doppler Sensors are used in a variety of industries, from automotive manufacturing to medical imaging.

Moor instruments is a world leader in the design, manufacture and distribution of monitoring and imaging systems to assess blood flow and oxygen in the microvasculature.
