Abstract
The projection device includes a light source, a liquid crystal on silicon (LCoS) panel, and a circuit. The circuit is configured to obtain a target image including a target pattern, and generate two content images. Each content image includes a duplicated pattern of the target pattern, and the duplicated patterns are off-axis shifted to the same coordinate when performing a computer-generated hologram (CGH) algorithm, so as to generate a phase image. The LCoS panel is driven according to the phase image to display a reconstructive image at a reconstructive distance.
