Abstract

We proposed a modified superpixel method that is capable of complex amplitude spatial light modulation for multi-wavelength simultaneously with a single binary hologram on DMD. We demonstrate it in color holographic display and structured beam generation, by both simulation and experiments. For the holographic display, multiple characters are displayed in different depths as expected, with a relatively low speckle noise. With the high refresh rate of DMD, the method can realize a dynamic flickering-less display. Our research brings the superpixel method into a multi-color regime and will find its applications in various areas.
