Abstract
In one embodiment, a system and method for performing single-shot digital holography include an optical hybrid assembly configured to receive a reference beam from a light source and another beam, and a balanced detector comprising multiple sensor arrays that are configured to receive outputs of the optical hybrid assembly and simultaneously measure in-phase and quadrature components of an incoming light wavefront that results from interference between the reference beam and the other beam within the optical hybrid assembly to provide a full set of digital holograms in a single exposure.
Claims25
A system for performing single-shot digital holography, the system comprising:
- an optical hybrid assembly configured to receive a reference beam from a light source and another beam;
- and
- a balanced detector comprising multiple sensor arrays that are configured to receive outputs of the optical hybrid assembly and simultaneously measure in-phase and quadrature components of an incoming light wavefront that results from interference between the reference beam and the other beam within the optical hybrid assembly to provide a full set of digital holograms in a single exposure.
A method for performing digital holography, the method comprising:
- receiving a reference beam from a light source and another beam;
- interfering the reference beam and the other beam to generate an interference wavefront and separating the wavefront into its in-phase and quadrature components;
- and
- simultaneously measuring the in-phase and quadrature components of the wavefront to obtain a full set of digital holograms in a single exposure.
A method for performing backward light propagation, the method comprising:
- receiving a reference beam from a light source and an object beam from a target object;
- interfering the reference beam and the object beam to generate an interference wavefront and separating the wavefront into its in-phase and quadrature components;
- simultaneously measuring the in-phase and quadrature components of the wavefront to obtain a full set of digital holograms in a single exposure;
- and
- performing electronic phase conjugation on the measured wavefront components to obtain the complex conjugate of the wavefront.
