Color Fourier orthoscopic holography with laser capture and an LED display

We present an end-to-end full color Fourier holographic imaging approach, which involves standard holographic recording with three wavelengths and an improved LED-driven display. It provides almost undistorted orthoscopic reconstruction of large objects in full color, which can be viewed with a naked eye. High quality reconstruction is preserved across large object depths, measured in meters, as shown theoretically and experimentally. Our imaging approach is based on capture, processing and display of the object wave fields without spherical phase factors. This efficient convention combined with a novel numerical propagator for confocal fields enables complete axial decoupling of both ends of the imaging chain, and consequently, free manipulation of axial position as well as size of the image without visible deformations and with minimal computation effort.
