Holography

In holographic displays, binary spatial light modulators such as DMD and FLCoS are widely used due to their simple mechanisms and capability for high-speed operation. However, their extremely limited bit depth results in degraded image quality. While iterative optimization methods have been used to improve image quality, they require significant computational time. This research proposes a method that incorporates deep unfolding into iterative optimization to enhance both image quality and computational speed.
