We present a novel method of producing arbitrarily valued binary phase-only modulation from a commercially available ferroelectric liquid-crystal spatial light modulator that is used in conjunction with simple polarization components. By cascading of such stages, modulators with four and eight equally spaced phase levels are constructed with 128 × 128 pixels. Near-diffraction-limited performance, when stopped down to 64 × 64 pixels, is reported in producing simple diffraction patterns and when used to generate asymmetric spot arrays in the Fourier plane of a lens.
我们提出了一种新颖的方法，可从市售铁电液晶空间光调制器产生任意值的仅二值相位调制，该调制器与简单的偏振组件配合使用。通过级联这些阶段，构建了具有128×128像素的具有四个和八个等间距相位级别的调制器。据报道，当缩小到64×64像素时，在产生简单衍射图案以及用于在透镜的傅里叶平面中生成不对称光斑阵列时，具有接近衍射极限的性能。
