无衍射限制的智能光传感器

Brainy light sensors with no diffraction limitations

H. J. Caulfild, L. P. Yaroslavsky, Jacques Ludman

摘要:

在完全不知道场景包含什么的情况下,成像系统非常有用。但是,如果我们知道场景将由不超过几个遥远的点源组成,非成像系统可能会以更小,更坚固,更便宜的方式实现更好的精度。我们在这里展示了这些优点可以在各种各样的设计中实现。在适当的条件下,它们都可以突破衍射极限。我们称这些传感器为“智能”,类似于阿尼玛;视觉使用由一台奇妙的计算机-大脑处理的可怜的光学系统。

英文摘要:

In total ignorance of what a scene contains, imaging systems are extremely useful. But if we know the scene will be comprised of no more than a few distant point sources, nonimaging systems may achieve better accuracy in a smaller, more rugged, and less expensive manner. We show here that those advantages can be realized in a wide variety of designs. All can beat the diffraction limit under the proper circumstances. We call these sensors "brainy" in analogy to anima; vision which uses poor optics processed by a wonderful computer - a brain.
