[期刊论文] 作者:YijunQi,ChenliangChang,andJunXia, 来源:ChineseOpticsLetters 年份:2017
A method is proposed to realize accurate spatial complex modulation based on the spatial cross-modulation method (SCMM) via a phase-only spatial light modulator. The conventional SCMM cannot achieve high quality reconstruction, especially w......

The nonuniform sampling method in hologram plane is proposed to reconstruct objects on multi-plane simultaneously. The hologram is nonuniformly sampled by decomposing it into several parts with various sampling rates. The hologram is calcul......

In liquid crystal spatial light modulator (SLM)-based holographic projection, the image is usually displayed at a distant projection screen through free space diffraction from a computer-generated hologram (CGH). Therefore, it allows for re......

We present a highly efficient method of generating and shaping ellipse perfect vector beams (EPVBs) with a prescribed ellipse intensity profile and continuously variant linear polarization state. The scheme is based on the coaxial superposi......
