Abstract: Disclosed herein is a display device including at least one illumination source configured for projecting at least one illumination beam on at least one scene; at least one optical sensor having at least one light sensitive area, where the optical sensor is configured for measuring at least one reflection light beam generated by the scene in response to illumination by the illumination beam; at least one translucent display configured for displaying information, where the illumination source and the optical sensor are placed in direction of propagation of the illumination light beam in front of the display, and at least one control unit, where the control unit is configured for turning off the display in an area of the illumination source during illumination and/or in an area of the optical sensor during measuring.

Abstract: A detector for object recognition includes an illumination source for projecting an illumination pattern on an area including at least one object; an optical sensor having a light-sensitive area and configured for determining a first image including a two-dimensional image of the area, and a second image including a plurality of reflection features generated in response to illumination, each reflection feature including a beam profile; an evaluation device for determining beam profile information for each reflection feature by analyzing their beam profiles, determining a three-dimensional image using the determined beam profile information, identifying the reflection features located inside and/or outside an image region, determining a depth level from the beam profile information of the reflection features located inside and/or outside of the image region, determining a material property of the object from the beam profile information, and determining a position and/or orientation of the object.

Abstract: Disclosed herein is a light module and a method for operating the light module. The light module includes a light source; an electronic circuit for driving the light source; where the electronic circuit includes a current source, where the current source is designated for generating and controlling a control current for driving the light source, and a protection controller, where the protection controller is designated for interrupting the control current to the light source in an event in which the current source fails. The light module and the related method address an eye-safe operation of the light module, specifically for a laser light source included by the light module to achieve compliance to laser safety class 1.

Abstract: Described herein is a projector for illuminating at least one object with at least two illumination patterns. The projector includes at least one tunable laser source and at least one diffractive optical element. The projector is configured to generate the at least two illumination patterns each including a plurality of illumination features by controlling at least one property of the tunable laser source. The projector includes at least one control unit. The control unit is configured for controlling the at least one property of the tunable laser source.
