A method for high-quality reconstruction and autofocusing in Fresnel zone aperture (FZA) encoded lensless imaging is proposed. By examining the image sharpness on the back propagation, the accurate focusing distance and PSF considering diffraction can be calculated. Then we can use a TV regularization-based compressive sensing method to suppress the twin image.
