Patent number: 12222679Abstract: A holographic wavefront printing system and method are provided. A two-dimension digital blazed grating is loaded on a phase hologram, and the emergent direction of active region diffracted light is adjusted to prevent overlapping with the dead region diffracted light after being Fourier transformed by a lens, and a phase spatial light modulator is inclined by a preset angle to change the emergent direction of the diffracted light, such that the dead region zeroth-order and first-order diffracted light on a focusing surface are symmetrical with respect to a main optical axis of a first lens, the frequency spectrum center of active region zeroth-order diffracted light is then loaded to the original frequency spectrum center without information change. In this way, the adverse effects of the dead region diffracted light and active region high-order diffracted light of the phase spatial light modulator on holographic wavefront printing are eliminated.Type: GrantFiled: October 26, 2022Date of Patent: February 11, 2025Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Xiaolin Xie, Jinlun Zhou, Haiyan Peng, Yun Zhang, Huamin Zhou, Mingli Ni, Xingping Zhou
