Abstract
A three-dimensional imaging system uses a single primary optical lens along with various configurations of apertures, refocusing facilities, and the like to obtain three offset optical channels each of which can be separately captured with an optical sensor.
Claims21
A camera comprising:
- a primary optical facility having a single primary optical lens and an optical path with a center axis;
- an aperture element including a plurality of apertures for selectively transmitting portions of the optical path to provide a plurality of optical channels, one of the plurality of apertures positioned on the center axis between the single primary optical lens and an optical sensor;
- a refocusing facility including a plurality of refocusing lenses, each one of the refocusing lenses at a conjugate position in the optical path to one of the plurality of apertures;
- and
- a sampling facility that directs one or more of the plurality of optical channels toward the optical sensor, the sampling facility including at least one prism having a hole positioned on the center axis, the hole passing a center one of the plurality of optical channels.
