Fig. 1: Concept of the achromatic holography with large viewing angle.
From: Advances in large viewing angle and achromatic 3D holography
The red, green, and blue lasers are incident on the time-sequenced hologram patterns on the SLM, and the RGB holographic images are projected on the three predefined sections on the color liquid crystal grating. The RGB images are further diffracted to multiple diffraction orders. Finally, the achromatic holographic display with a large view angle is demonstrated
