• A blue white He-Cd laser composed of three R/G/B component beams is directly applied to fabricate the optical Fourier transform hologram (OFTH). The visual appearance of reconstructed color hologram images is discussed in contrast to that of an ordinary OFTH which is fabricated using a monochromatic He-Ne laser and diode-pumped solid state(Nd:YAG)laser. The characteristic of He-Cd laser is checked from the viewpoint of the visual size and its place of reconstructed color ghost image called cross talk in the reconstruction process. The visual effect of reconstructed hologram ghost image which can be digitally modified and emphasized by means of commercially available software is discussed through this study.
