Zero-order-free complex beam shaping
In this paper, we report a new approach for zero-order free beam shaping by designing an asymmetric triangle reflector and introducing a digital blazed grating and a digital lens to the phase
Zero order suppression on computer generated hologram produced by
We investigated ZOD sources in two different CGH systems and suggested different methods to remove the ZOD in each system. Two types of spatial light modulator (SLM) were employed for different type
Suppression of Zeroth-Order Diffraction in Phase-Only Spatial
Abstract: We suppress the unwanted zeroth order diffraction (ZOD) contributed by the dead areas of a spatial light modulator with a correction beam that is independently created from the de sired target.
Eliminating zeroth-order light of spatial light modulator with voltage
In this investigation, we report that by properly adjusting the high-level and low-level pixel voltages of an SLM, the zeroth-order light caused by the pixelation effect of SLM can be significantly eliminated.
