Abstract

We investigated coherent imaging with a binary off-axis resonance domain diffractive lens using three lasers in visible wavelengths. The relations between the dispersion of this lens, shape of its point spread function, and spectral properties of these lasers were analyzed theoretically and experimentally. In particular, wemeasured the point spread function, imaging contrast, and diffraction efficiency. Experimental results proved the feasibility of imaging with low distortion and more than 83% diffraction efficiency in laser light.
