Tzu-An Chou;Chih-Hao Chuang;Isaac Manyonge Matere;Cathy Weng;Hoang-Yan Lin;Chien-Yu Chen

Recently there have been development in digital optics especially in laser beam machining, however designing miniaturized is still a challenge. We offer a solution by use of modified Gerchberg-Saxton algorithm to create computer generated holography that can focus a multi-focus spot light on four different focal planes.
