Abstract: A method for determining a range to a target comprises rotating a mirror unit around a scan axis. A light pulse is reflected off of a transmitting portion of the mirror unit toward the target. A light pulse, received from the target, is reflected off of a receiving portion of the mirror unit toward a receiver. The method includes compensating for a lag angle, caused by the rotation of the mirror unit around the axis, between the time the light pulse is reflected from the transmitting portion and the time the received light pulse is reflected from the receiving portion. The compensation includes angularly offsetting the transmitting portion about the scan axis from a surface plane of the receiving portion.

Abstract: A block arrangement of optical elements is provided for use as a transmitter/receiver for a light detection and ranging (LIDAR) system. The block arrangement comprises: a plurality of glass modules aligned together as a block to form a plurality of optical paths therein and secured together to maintain said alignment; a collimated light source secured to said block for generating a coherent beam of light over at least one optical path in said block which guides said coherent beam of light to an exit point of said block; and a light detector secured to said block. The block serves for receiving a return coherent beam of light and is configured to conduct said return coherent beam of light to the light detector over at least one other optical path formed in said block.

Abstract: Un appareil combiné à laser pour déterminer à la fois l'altitude et la vitesse au sol d'un aéronef, ledit appareil comprenant une source de laser (30) pulsé ; une pluralité de premiers éléments optiques (46, 48) pour diriger des faisceaux laser ; une pluralité de deuxièmes éléments optiques configurés pour former un télescope (52); un scanneur optique (84) pour diriger les faisceaux laser et le champ optique du télescope (52) vers des positions au sol souhaitées ; le télescope (52) étant adapté pour recevoir des réflexions par le sol décalées de longueur d'onde par effet Doppler des faisceaux laser pulsés ; un élément de filtre optique pour séparer les réflexions en première et deuxième parties qui dépendent du décalage en longueur d'onde par effet Doppler ; et des moyens de traitement pour déterminer l'altitude et la vitesse au sol de l'aéronef en se basant sur les première et deuxième parties.
