Abstract
The disclosure is directed to providing high resolution stereoscopy with extended depth of focus. Wave front coding in optical paths going to a first detector and at least a second detector may be implemented to affect an intermediate set of images. The intermediate set of images may be filtered (i.e. decoded) to produce a filtered set of images with selected resolution and depth of focus properties. A first filtered image and a second filtered image may be substantially simultaneously presented to respective first and second eyes of an observer to further generate an illusion of enhanced depth (i.e. 3D perception).
