摘要: A controller (7) is disclosed for controlling the power supply to a laser (3) that is used in determining the motion of an object (8). The controller comprises a power source (2) that is arranged to supply power pulses (10, 11) to the laser (3) in response to a controller signal. The controller (7) controls the generation of pulses to those periods in which a reliable result can be obtained, by detecting the laser radiation that has interacted with pulses reflected from the object (8), in order to conserve power consumption. Further the power pulses (10, 11) comprise a heating component (9), which serves to stabilize the temperature of the laser (3) and therefore calibrate the laser (3) so that a known lasing wavelength is generated.
