依据基模(TEM00)高斯光束本身的横向光强分布,结合一类光强分布转换器件的转换特性,提出一种实用型低能耗光学超分辨的新方案。高斯光中央峰入射这类器件后,将从该器件的边缘出射,而入射到边缘的光则从中央出射,由此,在成像系统中就可实现光学超分辨,与原有的滤波器比较,大大降低了能量的损耗。

A novel practical configuration for superresolution is presented,which relies on the polar reversal property of some irradiance redistribution elements and the profile of TEM00 mode Gaussian laser beam.Gaussian peak of incident light coming into the central part of such element,may go out from near the peripheral part of element,and the skirt of Gaussian beam coming into peripheral part goes out from central part.Thus,the optical superresolution is obtained in an imaging system.Compared with the filter,the energy loss is greatly diminished and the deserted light energy is recovered.
