Abstract
Provided are an optical sensing system and an optical apparatus including the same. The optical sensing system may include a light output part configured to emit a laser beam to an object, and a sensing part configured to sense a laser beam emitted from the light output part and reflected from the object. The sensing part may include a photodetector and the active optical device located on an optical path between the photodetector and the object. The active optical device may actively control an orientation of a laser beam passing therethrough and may include a material layer having a refractive index which is changeable by application of an electrical signal.
Claims23
An optical sensing system comprising:
- a light output part configured to emit light;
- and
- a sensing part configured to sense light emitted from the light output part and reflected from an object,
- wherein the sensing part comprises:
- a photodetector;
- and
- an active optical device disposed on an optical path between the photodetector and the object,
- wherein the active optical device is configured to control an orientation of light transmitted therethrough.
An optical sensing system comprising:
- a light output part configured to output light;
- and
- a sensing part comprising:
- a photodetector, and
- a beam steering device comprising an active optical material having an optical property which changes upon application of at least one of an electrical signal, a magnetic signal, and heat, wherein the beam steering device is configured to control a direction of light transmitted therethrough, such that light transmitted therethrough is incident on the photodetector.
