Abstract
A holographic imaging system for capturing and displaying a high-resolution and polychromatic hologram, the holographic imaging system comprising: a plurality of monochromatic coherent light sources, configured to generate a plurality of monochromatic light input wavelengths; a polarization preserving diffuser configured to receive the plurality of monochromatic light input wavelengths at a first end of the polarization preserving diffuser, and further configured to provide a polychromatic output at a second end of the fiber; and a diffractive optical element configured to receive polychromatic light from the second end of the fiber.

A holographic imaging system comprising:
- a plurality of monochromatic coherent light sources, configured to generate a plurality of monochromatic light input wavelengths;
- a polarization preserving diffuser configured to receive the plurality of monochromatic light input wavelengths at a first end of the polarization preserving diffuser, and further configured to provide a polychromatic output at a second end of the polarization preserving diffuser;
- and
- a diffractive optical element configured to receive polychromatic light from the second end of the polarization preserving diffuser.
A method of holographic imaging an object, the method comprising:
- generating a plurality of monochromatic light input wavelengths using a plurality of coherent light sources;
- modifying, using a polarization maintaining diffuser, a spatial profile of the plurality of monochromatic light input wavelengths to generate a polychromatic output;
- and
- providing the polychromatic output to a diffractive optical element for holography.
A holographic imaging system comprising:
- a monochromatic coherent light source, configured to generate a monochromatic input light;
- a multimode optical fiber configured to receive the monochromatic input light at a first end of the multimode optical fiber, and further configured to provide output light from a second end of the fiber;
- and
- a diffractive optical element configured to receive the output light from the second end of the fiber.
