Embodiment Construction

[0557] exist figure 1 , a first exemplary embodiment of an optical detector 110 according to the invention is shown in a highly schematic cross-sectional view in a plane parallel to the optical axis 112 of the optical detector 110 . The optical detector 110 may be used to detect a scene 114 or a portion thereof, wherein the scene 114 refers to a surrounding 116 of the optical detector 110 in which an image of the scene 114 or a portion thereof may be taken. At least one image of scene 114 or a portion thereof may comprise a single image or a progressive sequence of images, such as a video or video clip. In this particular example, the scene simply includes object 118 . Object 118 may be adapted to emit and / or reflect one or more light beams 120 towards optical detector 110 .

[0558]The optical detector 110 comprises at least one optical sensor 122 , which is embodied as a FiP sensor, ie because the optical sensor 122 has a sensor area 124 which can be illuminated by a light...

Abstract

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).

Description

technical field [0001] The invention is based on the general idea concerning optical detectors as proposed for example in WO 2012 / 110924 A1, US 2012 / 0206336 A1, WO 2014 / 097181 A1, US 2014 / 0291480 A1 or WO 2015 / 024871 A1, all of which The entire contents are incorporated herein by reference. [0002] The invention relates to an optical detector, a detector system and an optical detection method, in particular for determining the position of at least one object. The invention further relates to various uses of human-machine interfaces, entertainment devices, tracking systems, scanning systems, cameras and optical detectors for exchanging at least one item of information between a user and a machine. The devices, systems, methods and uses according to the invention can in particular be used, for example, in everyday life, games, traffic technology, production technology, safety technology, photography such as digital photography or artistic video photography, documentation or te...
