A photographic and reproduction technique for the transmission-type genuine colour hologram is disclosed. According to colour level of the object to be taken up, red, green and blue laser beams or red and green laser beams are used to record the colour information of the said object on a same holographic record material and at same time by different beams in different directions. When it is reproduced, the same laser beams are used to radiate the hologram in their original directions, so reproducing original genuine colours. Its advantages include high-brightness reproduction, high sensitivity and large size. |
