Abstract: 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.

Abstract: A camera (110) for recording at least one image of at least one object (112) is proposed. The camera (110) comprises: —at least one converging element (128), wherein the converging element (128) is adapted to converge a light beam (132) passing through the converging element (128) to travel along a beam path to be received by at least one optical sensor (114); —at least one first aperture element (130) having a first adjustable area (136), wherein the first aperture element (130) is located in the beam path between the converging element (128) and the optical sensor (114); —at least one second aperture element (134) having a second adjustable area (138), wherein the second aperture element (134) is located in the beam path between the first aperture element (130) and the optical sensor (114); —the at least one optical sensor (114) being adapted for receiving the light beam (132), wherein the optical sensor (114) is further adapted to generate at least one first picture in a first setting comprising the first aperture area (136) exceeding the second aperture area (138) and to generate at least one second picture in a second setting comprising the second aperture area (138) exceeding the first aperture area (134); and —at least one evaluation device (142) designed to generate at least one three-dimensional image of the at least one object (112) by comparing the at least one first picture and the at least one second picture. Thereby, a simple and, still, efficient three-dimensional camera (110) for an accurate recording of an image of at least one object (112) in space is provided.
