Abstract
A dual sinusoidal modulation scheme introducing directional sensing of a laser Doppler velocimeter (LDV) employing a semiconductor laser source is described. With this technique using direct current modulation a single-sideband Doppler shift of 8.5 MHz with an image sideband suppression of 29dB is demonstrated.Keywords
