DOI: 10.1117/1.oe.56.5.053103

Abstract: Abstract. A method is proposed to suppress speckle noise using only part of the pixels in a single-exposure digital hologram. Different holographic patterns are first generated from a single-exposure digital hologram using specially designed binary… read more here.

DOI: 10.1364/ao.403534

Abstract: In a digital hologram, the maximum viewing angle of a computer-generated hologram (CGH) is limited by pixel pitch due to the diffraction grating equation. Since reducing pixel size of display panel is challenging and costly,… read more here.
