论文摘要
由于空间光调制器（SLM）的像素化效应引起的至关重要的零阶光在光调制领域一直是一个严重的问题，尤其是在具有高数值光圈光学系统的应用中。在这项研究中，我们报告说，通过正确调整SLM的高级和低级像素电压，可以显着消除由SLM的像素化效应引起的零阶光。该方法在倒荧光显微镜中得到进一步验证。实验结果表明，零阶光最多可抑制91.3％，并伴随着调制效率从77.5％提高到92.6％。
The crucial zeroth-order light due to the pixelation effect of spatial light modulator (SLM) has been a serious issue in the field of light modulation, especially in applications with a high numerical aperture optical system. In this investigation, we report that by properly adjusting the high-level and low-level pixel voltages of an SLM, the zeroth-order light caused by the pixelation effect of SLM can be significantly eliminated. The method is further validated in an inverted fluorescence microscope. The experimental results show that the zeroth-order light can be inhibited up to 91.3%, accompanied by an improvement of the modulation efficiency from 77.5% to 92.6%.
