Abstract

The crosstalk problem between the background light and the signal light of the diffractive optical element severely degrades the image quality and limits the practical application. In this paper, we proposed an off-axis imaging technology aimed at multifocal diffractive lenses and performed geometrical imaging analysis to investigate the imaging distribution. Off-axis imaging ensured a high signal-to-noise ratio by separating the signal and the noise spatially and provided a larger space for parallel synchronization processing in different image plane. Taking the bifocal Greek-ladder lens as an example, the experiment achieved zero-crosstalk multiplanar images and verified the law of diffractive imaging. Besides, the critical condition for zero-crosstalk imaging was also studied.
