Abstract

When fabricating a large area holographic diﬀuser by cascading hologram of diﬀusion patterns with speciﬁed area, it was found that a ﬂuctuation of diﬀraction intensity occurred at the boundaries of the two adjacent exposed areas. It was aﬃrmed experimentally that this problem could be alleviated by controlling the intensity distribution of reference laser beam around the boundary of each exposure area. Using this method, the ﬂuctuation was reduced considerably. For better compensation of the non-uniformity a theoretical analysis for the diﬀusion process of photopolymer is discussed and compared with the experimental results.
