摘要： A light detection device includes a diffraction element and a light detection element. The diffraction element diffracts a beam of light that is incident on the diffraction element. The light detection element includes light receivers to receive diffracted light. The diffraction element generates beams of the diffracted light by dividing the beam of light. The light detection element determines a displacement of the beam of light relative to the diffraction element on the basis of quantities of light of the beams of the diffracted light. The light detection element determines an angle change of the beam of light relative to the diffraction element by dividing the quantity of light of one of the beams of the diffracted light.

摘要： A system for remotely sensing light from within a monitored environment containing one or more retro-reflective optical elements. The system includes an illuminator including a light source and a reflector unit comprising a deformable mirror arranged to receive light from the light source and to reflect the received light. This outputs illumination light from the illuminator for illuminating the optical element(s) within the monitored environment. A detector is arranged to receive light returned by the one or more retro-reflective optical elements in response to the illumination light. The detector determines a wavefront of the returned light and detects a property of the monitored environment according to the returned light. The reflector unit is arranged to deform the deformable mirror according to the determined wavefront such that light from the light source is reflected by the deformable mirror so deformed to output illumination light with a modified wavefront.

摘要： The present invention relates to a lidar measurement system for the detection of the presence and/or motion of particles and/or objects in a space region remote from the lidar measurement system and comprising an interferometer arrangement, as well as to a corresponding method using such a measurement system. The interferometer arrangement comprises a continuous wave laser source (2), a photodetector arrangement (7), and optical components which are adapted to split light (23) emitted by the continuous wave laser source (2), to guide it along a first optical path constituting a measurement branch (4) and along a second optical path, which is separate from the first optical path and constitutes a reference branch (5), and to eventually have it incident in a spatially coherently superimposed manner onto the photodetector arrangement (7). The reference branch (5) has a predetermined optical path length, and the measurement branch (4) comprises a measurement portion (16), in which the light is directed away from the measurement system towards a space region remote from the measurement system and passes through the space region and light backscattered towards the measurement system by particles present in the space region is received again at the measurement system. Further, an evaluation unit (9) is provided which is coupled to the photodetector arrangement (7) and is adapted to receive the detector signal thereof and to determine from the detector signal the presence and/or movement of particles in the remote space region. The continuous wave laser source (2) has a coherence length in the range of 0.1 to 100 m.
