摘要： A detector (110, 1110, 2110) for determining a position of at least one object (112) is proposed. The detector (110, 1110, 2110) comprises: at least one transfer device (128, 1128), wherein the transfer device (128, 1128) has at least one focal length in response to at least one incident light beam (116, 1116) propagating from the object (112, 1112) to the detector (110, 1110, 2110); at least two optical sensors (113, 1118, 1120), wherein each optical sensor (113, 1118, 1120) has at least one light sensitive area (121, 1122, 1124), wherein each optical sensor (113, 1118, 1120) is designed to generate at least one sensor signal in response to an illumination of its respective light-sensitive area by the light beam (116, 1116), at least one evaluation device (132, 1132) being configured for determining at least one longitudinal coordinate z of the object (112, 1112) by evaluating a quotient signal Q from the sensor signals. The detector is adapted to determine the longitudinal coordinate z of the object in at least one measurement range independent from the object size in an object plane.

摘要： Described herein is a detector for determining a position of an object. The detector includes a sensor element having a matrix of optical sensors, wherein the sensor element is configured to determine a reflection image. The detector also includes an evaluation device configured to select a reflection feature of the reflection image at a first image position in the reflection image, determine a longitudinal coordinate z of the selected reflection feature by optimizing a blurring function fa, and determine a reference feature in a reference image at a second image position in the reference image corresponding to the reflection feature. The reference image and the reflection image are determined at two different spatial configurations, wherein the spatial configurations differ by a relative spatial constellation, wherein the evaluation device is configured to determine the relative spatial constellation from the longitudinal coordinate z and the first and the second image positions.

摘要： Described herein is a detector for determining a position of an object. The detector includes a sensor element having a matrix of optical sensors, each designed to generate a sensor signal in response to an illumination of its light-sensitive area by a light beam propagating from the object to the detector. The detector also includes an evaluation device configured to select a region of interest of the matrix, respectively determine a sensor signal of at least two optical sensors of the region of interest, and determine a longitudinal coordinate zDPR of the object by evaluating a combined sensor signal Q. The evaluation device is also configured to determine an image of the region of interest from the sensor signals, determine a longitudinal coordinate zDFD of the object by optimizing at least one blurring function fa, and determine combined distance information z considering the longitudinal coordinates zDPR and zDFD.

摘要： A method for adjusting a detector (110) for determining a position of at least one object (112) within a range of measurement (114) is disclosed. The detector (110) comprises at least two longitudinal optical sensors (116) and at least one transfer device (118) for imaging the object (112) into an image plane. The transfer device (118) has a focal plane. The transfer device (118) is positioned in between the longitudinal optical sensors (116) and the object (112). Each of the longitudinal optical sensors (116) has at least one sensor region (120). Each of the longitudinal optical sensors (116) is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the respective sensor region (120) by at least one light beam (178) propagating from the object (112) to the detector (110), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam (178) in the sensor region (120). The detector (110) further comprises at least one evaluation device (124). The method comprises the following steps: (i) subsequently moving the object (112) longitudinally to at least two different calibration positions (134, 136) having at least two different longitudinal coordinates within the range of measurement (114); (ii) recording, for each of the calibration positions (134, 136), at least one first longitudinal sensor signal generated by a first longitudinal optical sensor (126) and at least one second longitudinal sensor signal generated by a second longitudinal optical sensor (128); (iii) forming, for each of the calibration positions (134, 126), at least one calibration signal using the first and second longitudinal sensor signals; (iv) generating a calibration function using the calibration signals, the calibration function defining a relationship between the longitudinal coordinate of the object (112) and the first and second longitudinal sensor signals.
