| description | A multichannel Light Detection And Ranging device with a dense array of equal spatial light modulator elements such as a digital micromirror device. The modulator array is arranged in a focal plane of a receiving optics between the receiving optics of a receiver unit and detectors. Each spatial light modulator element individually provides a first spatial modulation state and a second spatial modulation state, the two states differing in light redirection. Only in the first modulation state light from the receiving optics is redirected via a respective modulator element in a targeted manner towards a detector. The receiver unit comprises a dense array of juxtaposed optical wedges in between the modulator array and the detectors. Each wedge covers a different area of the modulator array and the refractive planes of the wedges are differently oriented. |
