摘要： In order to measure distances precisely, a receiver device for determining a distance from an object is proposed, comprising: a receiver having a semiconductor structure with a photosensitive region for generating photo-induced charge carriers, which region faces the rear side, and having a transportation region, which faces the front side, wherein the photosensitive region and the transportation region are spatially separated from one another by a separation layer which has a passage between the photosensitive region and the transportation region, wherein the transportation region has an arrangement of at least two gates lying one next to the other, at least one of the gates thereof being located in the overlapping region of the passage.

摘要： A flexibly usable optoelectronic sensor device for detecting an object, comprising a receiving device for receiving light backscattered after the scattering of an emitted light beam at the object, wherein the receiving device has an array of at least two receiving elements for detecting radiation and a receiving optical unit for imaging the received radiation on the array; the array is divisible and/or divided into at least two array regions, wherein the at least two array regions correspond in each case to scatterings at objects at different distances from the monitoring region and/or different brightnesses of the received radiation, and the receiving elements respectively arranged in different array regions are settable and/or set to detect with mutually different light sensitivities.

摘要： A rotary encoder system for registering the rotary angle position and/or angular speed of a rotary shaft which extends along an axis of rotation, including at least two optical marks at the rotary shaft, an optical sensor with a pixel matrix having pixel points, an imaging device for imaging each mark in a substantially axial direction on the pixel matrix as a mark image, and an evaluation device for reading and evaluating the pixel matrix in order to determine data in relation to the rotary angle position and/or angular speed. Further, the marks, the imaging device and pixel points are embodied in such a way that the mark images on the pixel matrix have at least the area of a pixel point, and the evaluation device is embodied to establish the location of the centroids of the mark images on the pixel matrix.
