Abstract
An optical emitter device includes an emitter array comprising a plurality of end-fire tapers, each end-fire taper configured to selectively emit a respective beam of light. A lens system is configured to shape and direct each beam of light based on a position of the respective end-fire taper relative to an optical axis of the lens system. A rotating reflector, including an axis of rotation perpendicular to the optical axis of the lens system, is configured to redirect and scan the beams of light through a scanning range.
Claims21
An optical emitter device comprising:
- an emitter array comprising a plurality of first point emitters, each respective first point emitter configured to emit a respective beam of output light, and configured to receive a respective beam of input light;
- at least one light source for generating the respective beams of output light;
- a first lens system configured to direct each respective beam of output light and each respective beam of input light based on a position of each respective first point emitter relative to a first optical axis of the first lens system;
- a rotating reflector configured to redirect each respective beam of output light, and configured to redirect each respective beam of input light towards the emitter array;
- and
- a polarization beam splitter for splitting each beam of input light into a first sub-beam having a first polarization mode and a second sub-beam having a second polarization mode, and for directing the first sub-beam towards a first photodetector circuit.
