Abstract
Transceiver head for a longitudinal Doppler speed indicator. Transceiver head for a longitudinal Doppler speed indicator with at least one pair of measuring axes. It comprises: a laser (1); polarization switching means (4) on the path of the laser beam; polarization separating means (5) on the path of the polarized beam that comes from the switching means; control means (5) for switching the switching means alternately from one state to another to direct the beam alternately to one measuring axis and then to another depending on its polarization state.
