Abstract
An optoelectronic device, in particular for the detection of obstacles and/or for distance measurement, may include a transmitting device for emitting laser beams. The transmitting device may include an array of pixels where each pixel of the pixel array comprises at least one laser, such as an optoelectronic laser, e.g. a VCSEL. The pixels of the pixel array may be divided into several sets of pixels, and the transmitting device may be configured to operate the sets of pixels in different, successive time intervals.
Claims26
An optoelectronic device for the detection of obstacles and/or for distance measurement, wherein the optoelectronic device comprises:
- a transmitting device for emitting laser beams, wherein the transmitting device comprises an array of pixels, wherein each pixel of the pixel array comprises at least one laser,
- wherein the pixels of the pixel array are divided into several sets of pixels,
- wherein each of the several sets of pixels comprises pixels that are spatially distributed across the array of pixels,
- wherein the transmitting device is configured to operate the sets of pixels at different, successive time intervals, such that during operation of a first set of pixels, the pixels of the other sets of pixels are not operated,
- wherein the transmitting device is configured to provide a simultaneous illumination of an entire target area via the laser beams from the respective pixels operated in a time interval,
- wherein the sets of pixels are activated in a random sequence, such that the sets of pixels are operated in a changing order in the different, successive time intervals, and
- wherein the pixel array comprises a plurality of segments each comprising a localized group of pixels, wherein each set of pixels comprises one pixel from each group of pixels.
An optoelectronic device for the detection of obstacles and/or for distance measurement, comprising:
