Sensor device for detecting an environment of a device, method for operating a sensor device for detecting an environment of a device and device with the sensor device

摘要

The invention relates to a sensor device (200) for detecting an environment of a device. The sensor device (200) has a first light source (212) for emitting first detection light (241) of a first light characteristic in a first solid angle range and a second light source (222) for emitting second detection light (242) of a second light characteristic in a second solid angle range . The first light characteristic and the second light characteristic differ from one another. The first solid angle range and the second solid angle range differ from one another. The sensor device (200) also has a holographic optical element (232) with a first imaging hologram and a second imaging hologram. The first imaging hologram and the second imaging hologram differ from one another. The first imaging hologram is designed to image first detection light (251) reflected on an object (OBJ) in the surroundings in the first imaging light. The second imaging hologram is designed to image second detection light (252) reflected on the object (OBJ) in second imaging light. The sensor device (200) also has a detector device (234) which is designed to receive the first imaging light and the second imaging light for detecting the surroundings of the device.
