In making a large size transmission type holographic screen for full color image projection. We revealed several factors that are the main reasons of image performance deterioration. Bragg condition fulfillment and emulsion shrinkage are decisive factors for governing the chromatic performance at the near edge of the screen. By considering these factors, developed optimum geometry for recording the large size holographic screen. The Bragg condition effect was analyzed quantitatively over the whole screen and it shows some colors aren't reproduced satisfactory at the screen edges. Recording condition and image projection condition are balanced properly and image quality is endhenced, by normally aligning line from reference beam source to projector at the screen center. And the recording setup was modified for compensating the photoplate emulsion shrinkage. Transmission type holographic screen of 40 cm X 60 cm was manufactured by using optimum recording setup. The screen has high brightness, and good color reproduction on the whole surface.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
