A white light source is employed for illuminating a color image hologram have no effect of diffusion. The primary or first order diffraction light is directed to and focused on a spectrum selecting spatial filter for selecting the spectra which contribute to form a multi-color image reconstructed by the hologram. The spatial filter is provided with a central slit of the width substantially equally to the band width of the spatial frequency peculiar to the object recorded and reconstructed. The spatial filter is further provided with a red filter and a blue filter on the opposite sides of the slit adjacent thereto. By providing the red and blue filters adjacent to the slit of the spatial filter, the brightness of the image reconstructed by the color halogram reconstructing system is markedly enhanced.

Device for reconstructing color holographic image

A card dispenser comprising a sheet-like optical information recording member bearing a number of indicia for a card recorded thereon, positioning means for moving the recording member in the plane thereof, an optical system for projecting the indicia recorded on the recording member onto a photographic photosensitive paper, means for feeding the photographic photosensitive paper through a focussing position of the optical means, means for processing the photosensitive paper, means for controlling the feeding means to selectively position the recording member at the optical focussing position of the optical system, and an input means for providing a signal to the controlling means for positioning the recording member at a selected indicia. Embodiments include additionally a display means for converting an electric image signal into a pattern, an optical system for also projecting the indicia indicated on the display means onto the photosensitive paper, and means for generating an electric image signal input into the display means.
