Abstract

The present invention provides improved Wavefront Coding imaging apparatus (100, 800, 1100) and methods composed of optics (102, 802, 1102), wavefront coding (104, 806, 1110), detection (106), and processing (112, 810, 1112) of the detected image. The optics are constructed and arranged to have the characteristic that the transverse ray intercept curves form substantially straight, sloped lines. The wavefront coding corrects for known or unknown amounts of 'misfocus-like' aberrations by altering the optical transfer function of the imaging apparatus in such a way that the altered optical transfer function is substantially insensitive to aberrations. Post processing then removes the effect of the coding, except for the invariance with regard to aberrations, producing clear images.
