Beschreibung
Zusammenfassung:	A continuous wave (CW) heterodyne light detection and ranging (LIDAR) air velocity sensor system that comprises a first light emitting structure arranged to send a signal light in a first direction in space; a second light emitting structure arranged to produce a local oscillator light having a wavelength different from the wavelength of the signal light by a predetermined wavelength; a receiver arranged to receive light from said first direction in space; and a first optical mixer for mixing the received light with said local oscillator light.
