Abstract

In this paper, a novel beam shaping configuration for confocal imaging system is presented, which relies on the reversal effect of axicons-component along with the Gaussian distribution of laser beam. The Gaussian peak of incident light coming into the one side of such component at the central part, may go out from the other side of component near the peripheral part, conversely, the skirt of Gaussian beam combing into the peripheral part may go out of the central part. Thus, the beam shaping is obtained with the component of cone axicons and therefore the superresolution can be realized in a confocal imagin system. Meanwhile, the energy loss is much diminished and the optical power deserted hitherto is recovered.
