Title
(EN) HOLOGRAPHIC LIGHT DETECTION AND RANGING
(ZH) 全息光探测和测距
Abstract
(EN)
A light detection and ranging system arranged to scan a scene comprises a light source arranged to output light having a first characteristic. A spatial light modulator is arranged to receive the light from the light source and output spatially-modulated light in accordance with computer-generated holograms represented thereon. A holographic controller is arranged to output a plurality of holograms to the spatial light modulator. Each hologram is arranged to form a corresponding light footprint within the scene. The holographic controller is further arranged to change the position of the lightfootprint within the scene. A light detector is arranged to receive light having the first characteristic from the scene and output a light response signal. The plurality of computer-generated holograms comprise a first plurality of holograms arranged to provide a first scan and a second plurality of holograms arranged to provide a second scan. In embodiments, the first plurality of holograms andsecond plurality of holograms are interleaved.
