Method and device for detecting motion

A method for detecting motion direction of an object (4) comprises the steps of: laser output light (L1) is generated, using a semiconductor laser (2) having a thermal response frequency (fr); the laser is driven with rectangularly modulated DC current (I) having a modulation frequency higher than s...
