光学检测器
摘要：
公开了一种光学检测器(110)，包括：至少一个光学传感器(122)，其适配于检测光束(120)并生成至少一个传感器信号，其中光学传感器(122)具有至少一个传感器区域(126)，其中光学传感器(122)的传感器信号取决于由光束(120)对传感器区域(126)的照射，其中，给定相同的照射总功率，传感器信号取决于光束(120)在传感器区域(126)中的宽度；至少一个可调焦透镜(128)，其位于光束(120)的至少一个束路径(130)中，可调焦透镜(128)适配于以受控的方式修改光束(120)的焦点位置；至少一个焦点调制装置(136)，其适配于向可调焦透镜(128)提供至少一个焦点调制信号(138)，从而调制所述焦点位置；至少一个成像装置(140)，其适配于记录图像；以及至少一个评估装置(142)，评估装置(142)适配于评估传感器信号，并且根据传感器信号，实现由成像装置(140)对图像的记录。
摘要（英）：

An optical detector(110) is disclosed, comprising: at least one optical sensor(122) adapted to detect a light beam(120) and to generate at least one sensor signal, wherein the optical sensor(122) has at least one sensor region(126), wherein the sensor signal of the optical sensor(122) is dependent on an illumination of the sensor region(126) by the light beam(120), wherein the sensor signal, given the same total power of the illumination, is dependent on a width of the light beam(120) in the sensor region(126); at least one focus-tunable lens(128) located in at least one beam path(130) of the light beam(120), the focus-tunable lens(128) being adapted to modify a focal position of the light beam(120) in a controlled fashion; at least one focus-modulation device(136) adapted to provide at least one focus-modulating signal(138) to the focus-tunable lens(128), thereby modulating the focal position; at least one imaging device(140) being adapted to record an image; and at least one evaluation device(142), the evaluation device(142) being adapted to evaluate the sensor signal and, depending on the sensor signal, to effect a recording of the image by the imaging device(140).
