One-dimensional superresolution optical system for temporally restricted objects

Objects that temporally vary slowly may be superresolved by use of moving gratings. A system of this kind had been proposed three decades ago. However, it provides some distortion of the spectral response of the resolved object. In this project, an enhanced method based on Dammann gratings instead of regular gratings is suggested. The modified approach achieves results with an undistorted output and relatively high light efficiency, and it is effective for both coherent and incoherent light. Experimental results are provided for demonstrating the ability of the new approach.
