摘要： The present invention relates to a measurement device (1) for the three-dimensional geometric capture of an environment by means of a plurality of transmission beams, wherein the transmission unit comprises multiple semiconductor lasers arrays (7,7A,7B,7C), each semiconductor laser array comprising multiple laser emitters (12, 12A, 12B) made from a monolithic block. The multiple semiconductor laser arrays (7,7A,7B,7C) are arranged and configured, e.g. by using an optical beam splitting component and/or by shifting or rotating the semiconductor laser arrays with respect to each other, such that an outgoing beam pattern (40) is generated, wherein the angular distance between adjacent beams of the outgoing beam pattern (40) is in each case less than or equal to a given minimal angular distance provided by the pitch between adjacent laser emitters (12, 12A, 12B) of the same semiconductor laser array.

摘要： The invention relates to a multichannel Light Detection And Ranging (LIDAR) device (4) with a dense array (1) of equal spatial light modulator elements (M, M1, M2) such as a digital micromirror device. The modulator array (1) is arranged in a focal plane of a receiving optics (20) between the receiving optics (20) of a receiver unit (29) and detectors (2, 2i, 2a-c). Each spatial light modulator element (M, M1, M2) individually provides a first spatial modulation state (1a) and a second spatial modulation state (1b), the two states differing in light redirection. Only in the first modulation state (1) light (10) from the receiving optics (20) is redirected via a respective modulator element (M, M1) in a targeted manner towards a detector (2, 2a-c). The receiver unit (29) comprises a dense array (3) of juxtaposed optical wedges (3i, 3a-c) in between the modulator array (1) and the detectors (2, 2i, 2a-c). Each wedge (3i, 3a-c) covers a different area (Ai, A1-A3) of the modulator array (1) and the refractive planes of the wedges (3a-c) are differently oriented, such that light coming from the modulator array (1) of modulator elements (M, M1) in the first modulation state (1a) is refracted area-wise in different refraction directions by the wedge array (3). The detectors (2a-c) are spatially separated from each according to a respective refraction direction (11i, 11a-c) each such that light of a respective modulator area (Ai, A1-A3) is receivable by a respective detector (2i, 2a-c).

摘要： The invention relates to a geodetic surveying device for measuring cooperative reflecting targets and diffusely reflecting targets. The carrier unit (5) of the surveying device is configured to provide at least three different distance measuring beams, each having a pre-defined beam shape and illuminating a spot area at the target. A first (9) of the three distance measuring beams has a divergence angle smaller than 1 mrad, a second (10) of the three distance measuring beams has a divergence angle within a divergence angle range ranging from 1 to 2 mrad, and a third (11) of the three distance measuring beams has a maximum divergence angle within a divergence angle range ranging from 2 to 15 mrad. The carrier unit is configured to detect returning parts of the third distance measuring beam with an associated maximum receiver field of view lying within a range ranging from 2 to 15 mrad. Thereby, the first distance measuring beam is used to measure diffusely reflecting targets by making a distance to a diffusely reflecting target determinable as a mean distance averaged over the illuminated spot area within the receiver field of view associated with the first distance measuring beam, the second distance measuring beam to measure cooperative reflecting targets, and the third distance measuring beam to measure diffusely reflecting targets by making a distance to a diffusely reflecting target determinable as a mean distance averaged over the illuminated spot area within the maximum receiver field of view associated with the third distance measuring beam.
