Abstract
A controller for controlling the power of a laser that is used in determining the motion of an object includes a power source that is arranged to supply power pulses to the laser in response to a controller signal. The controller controls the generation of pulses during periods in which a reliable result can be obtained, by detecting the laser radiation that has interacted with pulses reflected from the object, in order to conserve power consumption. Further the power pulses include a heating pulse portion, which serves to stabilize the temperature of the laser and calibrate the laser so that a known lasing wavelength is generated.
