摘要 波前编码技术是一种即可以提高系统成像质量又可以降低系统种类的"光学-数字"一体化的系统级成像技术,可以很好地控制离焦以及由离焦引起的像散、Petzval场曲、色差,还有由装调、温度漂移等引入的类似离焦的像差,在大视场、大焦深的条件下获得接近衍射极限的像质。介绍了波前编码技术的发展过程、理论基础、各国研究进展、应用前景等方面,并提出了目前存在的问题。 Wavefront Coding Technology is jointly optimized optical and digital imaging technology that can increase the performance and/or reduce the cost of modern imaging systems by reducing the effects of aberrations. Aberrations that can be controlled through Wavefront Coding include misfocus, astigmatism, field curvature, chromatic aberration, temperature related misfocus, and assembly related misfocus. We introduce the theory fundamental,development,research actuality and future application of Wavefront Coding ...
