Abstract
Three superimposed microholograms, corresponding respectively to the luminance, red chrominance and blue chrominance images, are recorded in respect of each color image. At the time of read-out, the illuminating beam is switched, at the rate of the line-scan function, between three separate positions and projects the above images on a single solid state vidicon. The read-out device can be adapted to an ordinary commercial color T.V. receiver.
