Abstract
A scanning optical device suitable for use as a camera or solar concentrator.
Claims10
An optical scanning apparatus comprising:
- a main waveguide structure formed as an elongated rectangle having a top surface and exit face;
- a main progressive delay layer disposed adjacent the top surface of the main waveguide;
- a second waveguide and second progressive delay layer disposed adjacent the exit face of the main waveguide, the second waveguide also having a top surface and an exit face;
- one or more detectors, disposed adjacent the exit face of the second waveguide;
- and
- wherein an index of refraction (ε) of the waveguides and/or progressive delay layers are adjustable, and
- wherein the progressive delay layers are provided by a series of varactors.
