A Real-Time Color Holographic Display System by Time Division Multiplexing Based on LCoS
A design of color holographic display system realized by using single chip liquid crystal on silicon (LCoS) is proposed. In this system, FPGA converts HDMI signal of the color hologram with frame rate of 60Hz to VGA signal of RGB holograms with frame rate of 180Hz and then output the signal to LCoS, at the same time, light the corresponding laser, which realizes a real-time time-division multiplexing color hologram display. In addition, in order to improve the linear phase characteristics of LCoS to get the better quality of hologram reconstruction, the analog calibration and flatness calibration are carried out. Finally, the feasibility of the system is verified by building the optical path and making color hologram.
