Abstract

A detector (110) for determining a position of at least one object (118) is proposed. The detector (110) comprises: —at least one optical sensor (112), the optical sensor (112) being configured to detect at least one light spot (156) generated by at least one light beam (150) propagating from the object (118) towards the detector (110), the optical sensor (112) having at least one matrix (152) of pixels (154), each pixel (154) being adapted to generate at least one pixel signal si,j in response to an illumination of the pixel (154) by the light beam (150); —at least one non-linearization device (123) configured to transform the pixel signals si,j of all pixels (154) i, j or of at least one group of pixels (154) into nonlinear pixel signals s′i,j, the nonlinear pixel signals s′i,j each being a nonlinear function of the power of the illumination pi,j of the respective pixel (154); —at least one summing device (125) configured to add up the nonlinearpixel signals s′i,j of all pixels (154) i, j or of the at least one group of pixels (154) and to generate at least one nonlinearsum signal S′=Σijs′ij; and —at least one evaluation device (126), the evaluation device (126) being configured …
