Adaptive optics in astronomical and other imaging systems allows compensation of aberrations introduced by random variations of the refractive index in the imaging path. I propose what I believe is a new type of adaptive optics system that dispenses with the hardware lenslet arrays and deformable mirrors of conventional systems. Theoretical and experimental studies show that wavefront sensing and compensation can be achieved by numerical processing of digital holograms of the incoherent object and a guide star. The incoherent digital holographic adaptive optics is seen to be particularly robust and efficient, with envisioned applications in astronomical imaging, as well as fluorescence microscopy and remote sensing.
天文和其他成像系统中的自适应光学技术可用于补偿成像路径中折射率随机变化引起的像差。我提出了一种新型自适应光学系统，它不需要传统系统中的硬件微透镜阵列和变形镜。理论和实验研究表明，通过对非相干物和导星的数字全息图进行数值处理，可以实现波前感应和补偿。这种非相干数字全息自适应光学系统具有很强的鲁棒性和高效性，预计可应用于天文成像、荧光显微镜和遥感等领域。
