The main drawback of a transmission type holographic screen is the color separation when the color images are projected on it due to its high dispersion. This drawback can be overcome by recording the screen with use of a long narrow slit type diffuser as an object. With the diffuser, a holographic screen of size 30 X 40cm2 has been recorded to display a full color stereoscopic image. The images displayed on the screen show a good resolution and are naturally colored, except near the edges of the screen. The color distortions in the edges of the screen are reduced by a lenticular sheet attached to the screen. The lenticular sheet enlarges the viewing zone. The image appears on the screen is bright enough to watch even in a normally illuminated room.

The main drawback of the use of transmission-type holographic screens is poor color reproduction caused by their high spectral dispersion. For overcoming this drawback, a long, narrow diffusing slit is used as an object when recording the screen. The necessary size and position of the slit relative to the photoplate and to the recording and reconstruction beams are determined by the phase relations of the beams. By use of the slit, holographic screens of 30 cm x 40 cm are recorded with a diverging reference beam and are used to display a multiview full-color stereoscopic image. The images displayed on the screen show no sign of color separation except near the edges of the screen. The image brightness on the screen is high enough that it can be watched in a normally illuminated room.
