LIGHT DETECTION AND RANGING SENSOR

An electro-optical device (18) includes a laser light source (20), which emits at least one beam of light pulses, a beam steering device (24), which transmits and scans the at least one beam across a target scene (22), and an array (28) of sensing elements (44). Each sensing element outputs a signal...

Beschreibung
Zusammenfassung:	An electro-optical device (18) includes a laser light source (20), which emits at least one beam of light pulses, a beam steering device (24), which transmits and scans the at least one beam across a target scene (22), and an array (28) of sensing elements (44). Each sensing element outputs a signal indicative of a time of incidence of a single photon on the sensing element. Light collection optics (27) image the target scene scanned by the transmitted beam onto the array. Circuitry (50) is coupled to actuate the sensing elements only in a selected region (70) of the array and to sweep the selected region over the array in synchronization with scanning of the at least one beam.
