METHODS AND SYSTEMS FOR PROGRAMMABLE OPTICAL DEPTH MODULATION VIA FIELD EVOLVING CAVITIES WITH POLARIZATION CLOCK

摘要

Some implementations of the disclosure are directed to modulating a number roundtrips that light travels with a cavity to modulate optical depth. In one implementation, a display system, comprises: a display configured to emit light corresponding to an image; a first optical component positioned in front of the display, the first optical component configured to pass the light to a field evolving cavity (FEC); and the FEC, wherein the FEC comprises a cavity entrance and a cavity exit, the cavity entrance configured to receive the light passed by the first optical component, the FEC configured with a polarization clock that modulates a number of round trips the light travels within the FEC, between the cavity entrance and the cavity exit, by changing a polarization of the light during each round trip.
