Abstract
Aspects of the present disclosure describe large scale steerable optical switched arrays that may be fabricated on a common substrate including many thousands or more emitters that may be arranged in a curved pattern at the focal plane of a lens thereby allowing the directional control of emitted light and selective reception of reflected light suitable for use in imaging, ranging, and sensing applications including accident avoidance.
Claims1
An optical structure comprising:
- a light source;
- a plurality of optical emitters;
- an optical power distribution network optically connecting the light source to the plurality of optical emitters, said optical power distribution network including a plurality of individually controllable switches;
- wherein said switches are configured such that optical power emitted from the light source that enters the optical power distribution network will be emitted from a single one of the plurality of optical emitters;
- wherein a portion of the emitted optical power is subsequently reflected by an object;
- wherein the reflected optical power portion is received by the single one of the emitters;
- and
- wherein the received reflected optical power is conveyed in an optical path of the distribution network, said received optical power path is the same as but in a reverse direction to an emitted optical path that the emitted optical power traversed from the light source to the one emitter.
