Abstract
Projection-type unidirectional holography is a promising three-dimensional imaging technique. However, the high cost of lasers in the reconstruction degrades its usefulness. This paper proposes a white-light-reconstruction version of the projection-type holography. The principle, design theory, and experiments are described. When a hologram is illuminated by a white light, the diffracted light exhibits color dispersion. The proposed method features the use of a holographically prepared diffraction grating for the compensation of the dispersion and of a simple device (called an optical channel) to cut off the nondiffracted components. Photographs of the reconstructed images show good agreement with the theory.
