Paper Abstract

An optimized encoding algorithm is required to produce high-quality computer generated holograms (CGH). For such purpose, we have proposed that usage of the direct search algorithm (DSA) is effective for encoding the Lohmann-type binary amplitude and phase CGH. However, it takes much time for a computation time to get an optical solution by a DSA. To solve this problem, we have newly found that simultaneously selective direct search algorithm (SDSA) is greatly effective to shorten a computing time for encoding a Lohmann-type CGH.
