Abstract
A fiber scanning projector includes a piezoelectric element and a scanning fiber passing through and mechanically coupled to the piezoelectric element. The scanning fiber emits light propagating along an optical path. The fiber scanning projector also includes a first polarization sensitive reflector disposed along and perpendicular to the optical path. The first polarization sensitive reflector includes an aperture and the scanning fiber passes through the aperture. The fiber scanning projector also includes a second polarization sensitive reflector disposed along and perpendicular to the optical path.
Claims20
A fiber scanning projector comprising:
- a piezoelectric element;
- a scanning fiber passing through and mechanically coupled to the piezoelectric element, wherein the scanning fiber is configured to emit light propagating along an optical path;
- a first polarization sensitive reflector disposed along and perpendicular to the optical path, wherein the first polarization sensitive reflector includes an aperture and the scanning fiber passes through the aperture;
- and
- a second polarization sensitive reflector disposed along and perpendicular to the optical path.
A method of generating light using a fiber scanning projector, the method comprising:
- generating light using a scanning fiber mechanically coupled to a piezoelectric element and passing through an aperture in a first polarization sensitive reflector;
- directing the light to propagate along an optical path;
- reflecting, during a first pass, the light off of a second polarization sensitive reflector disposed along the optical path;
- reflecting the light off of the first polarization sensitive reflector;
- and
- passing, during a second pass, the light through the second polarization sensitive reflector.
