论文摘要
我们在这里描述了一种生成高清任意激光束形状和对许多应用有用的方法，从光图和光刻到微观颗粒和超声原子的光学诱捕范围。二进制格栅与靶向强度分布之间的相对形对比度在空间光调节器上编码以控制光衍射，从而产生非常清晰，无斑点和光滑的图像。除了简单性（不需要其他相位板）外，该方法还通过直接的像素映射将图像直接编码在仅相位掩码上，从而允许更简单的反馈方案实时纠正和控制光线分布和光电位。
We describe here a method to generate high-definition arbitrary laser beam shapes and profiles useful to many applications, ranging from optical patterning and lithography to optical trapping of microscopic particles and ultracold atoms. The phase contrast between a binary grating and a targeted intensity distribution is encoded on a spatial light modulator to control light diffraction, producing very sharp, speckles-free, and smooth images. Besides simplicity, not requiring additional phase-plates, the method provides straightforward encoding of images onto phase-only masks by a direct pixel mapping, allowing simpler feedback schemes to correct and control light distributions and optical potentials in real-time.
