Abstract
A structured light projector includes a light source configured to emit light, a structured light pattern mask configured to receive the light emitted by the light source and including a first region configured to generate a first structured light having a first polarization and a second region configured to generate a second structured light having a second polarization that is different from the first polarization, and a polarization multiplexing deflector configured to deflect the first structured light and the second structured light generated by the structured light pattern mask, to different directions, respectively.
Claims27
A structured light projector comprising:
- a light source configured to emit light;
- a structured light pattern mask configured to receive the light emitted by the light source, the structured light pattern mask comprising a first region configured to generate a first structured light having a first polarization and a second region configured to generate a second structured light having a second polarization that is different from the first polarization;
- and
- a polarization multiplexing deflector configured to deflect the first structured light and the second structured light generated by the structured light pattern mask, to different directions, respectively.
An electronic apparatus comprising:
- a structured light projector;
- a sensor configured to receive light from an object which is irradiated with light emitted by the structured light projector;
- and
- a processor configured to obtain shape information of the object based on the light received by the sensor,
- wherein the structured light projector comprises:
- a light source configured to emit light;
