随着天文观测的深入，天文学家对天文望远镜自适应光学技术的需求越来越高，希望在短波段，校正大气湍流扰动，提高望远镜成像质量。然而，在短时间内，通过增加波前校正器的促动器数量，提高波前校正器和波前传感器的工作频率，突破现有自适应光学技术瓶颈，实现短波段的自适应光学校正，是不现实的。数字全息式自适应光学技术是一种新型的自适应光学技术，通过操作光波的振幅和相位，实现动态像差校正，改善天文望远镜成像质量。因而，天文望远镜数字全息自适应光学技术完全不需要波前校正器和波前传感器等硬件，而是完全采用数字办法处理，是一种十分具有发展潜力的自适应光学技术。该自适应光学技术非常切合我国天文自适应光学技术的现状，它的发展可以弥补我国在制造高性能波前校正器和波前传感器方面的不足，为我国新型天文自适应光学技术的发展提供理论基础和技术储备。

Adaptive optics has greatly attracted astronomers' interests because of its successful application in astronomical imaging in the past several decades. In order to obtain more information of the universe, they want to get images from telescopes with higher resolution in shorter wavelengths. However, it is almost impossible to achieve this goal through increasing the number of actuators of wavefront correctors and shortening the working cycle of wavefront correctors and wavefront sensors. Digital holographical adaptive optics is a novel technique, which could overcome the astronomical turbulence and improve the image quality of telescopes through manipulating the amplitudes and phases of waves. All the procedures of digital holographical adaptive optics are finished by digital methods, so there is no need of wavefront sensors and wavefront correctors. Now there is almost no wavefront correctors and wavefront sensors could used in astronomy to improve quality of telescope at visiual wavelength or shorter wavelength, and this problem could not solve in short time. However, to obtain high resolution images of universe at shoter wavelenth is extremely expected for all of the astronomers'. So the digital holographical adaptive optics is extremely suitable to develop in astronomy.
