| Popis: | Expressions for the quantization error in Hsueh-Sawchuk holograms are presented. These expressions suggest that the Hsueh-Sawchuk algorithm may be improved using a technique called prequantization. We demonstrate that the addition of prequantization reduces the quantization error in Hsueh-Sawchuk holograms by ∼25%. |
