Wave-front coding technology is a novel jointly optical and digital imaging technology which can greatly extend the depth of focus of optical systems. The image restoration process is an important part of wave-front coding technology. Using wave-front coding makes the modulation transfer function(MTF) values of the optical systems change little over a range of several times the depth of focus
which means the system MTF is quite insensitive to defocus
and there is no zero in the passband. So we can design a single filter for the restoration of images in different defocus positions. However
it's hard to avoid noise during image acquisition and transmission processes. These noises will be amplified in the image restoration
especially in the high frequency part when the MTF drop is relatively low. The restoration process significantly reduces the system signal to noise ratio this way. Aimed at the problem of noise amplification
a new algorithm was proposed which incorporated wavelet denoising into the iterative steps of Lucy-Richardson algorithm. Better restoration results were obtained through the new algorithm
effectively solving the noise amplification problem of original LR algorithm. Two sets of identical triplet imaging systems were designed
in one of which the cubic-phase-plate was added. Imaging experiments of the manufactured systems were carried
and the images of a traditional system and a wave-front coded system before and after decoding were compared. The results show that the designed wave-front coded system can extend the depth of focus by 40 times compared with the traditional system while maintaining the light flux and the image plane resolution. 2010 Copyright SPIE - The International Society for Optical Engineering.
