Paper Abstract

The use of hybrid optical-digital techniques facilitates improved optimisation of imaging systems. It involves the combined use of optical coding of an image using pupil-plane phase-modulation of the transmitted wavefront and postdetection digital decoding. Previous research in hybrid imaging tends to emphasize constancy of the modulation transfer function with aberrations and ignore the significant variations in the phase transfer function. We show that the restoration artefacts introduced by phase mismatch effects can also be used to deduce the defocus PSF, and when this is achieved, an overall improvement in image quality can be attained. Both numerical simulations and experimental images of hybrid imaging systems are presented.
