天文和其他成像系统中的自适应光学系统允许补偿由成像路径中的折射率随机变化引起的像差。我提出了一种我认为是一种新型的自适应光学系统，它省去了传统系统的硬件微透镜阵列和可变形反射镜。理论和实验研究表明，通过对非相干物体和导星的数字全息图进行数值处理，可以实现波前传感和补偿。非相干数字全息自适应光学被认为是特别坚固和有效的，在天文成像以及荧光显微镜和遥感中有望得到应用。(C)2012年美国光学学会
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.
