Abstract: A sensor system and a method for operating a sensor system are disclosed. In an one embodiment, the sensor system includes a light source configured to emit laser radiation and an optical element configured to image the laser radiation to at least one image point at a fixed distance in an optical far field of the sensor system. A detector is configured to detect a proportion of the laser radiation reflected back at at least one object illuminated by the laser radiation. A pin hole is located in front of the detector, a diameter of the pin hole corresponds to a size of the image point within a factor of 2.

Abstract: An optoelectronic sensor device and a method for operating an optoelectronic sensor device are disclosed. In an embodiment the optoelectronic sensor device includes a radiation-emitting semiconductor chip configured to emit radiation with a peak wavelength which depends on a temperature of the radiation-emitting semiconductor chip. The sensor device further includes a sensor chip configured to detect a part of the radiation reflected back to the sensor chip as well as a spectral filter component having an adjustable spectral transmission range. A wavelength determination unit is configured to determine the peak wavelength and a filter driver is configured to adjust the spectral transmission range to the determined peak wavelength.
