Detailed Description

Introduction

Cascaded propagation calculates a reconstructed complex wavefield at the retina plane given a source hologram in two steps: In the 1st step, the complex wave field is defined at the location of spatial light modulator and propagates to the viewing window taking account of a field lens. Then, to simulate the pupil, the wavefield at the viewing window is clipped by the aperture. Finally it passes through the eye lens and reaches the retina by the 2nd forward propagation. The eye lens can vary its shape to focus the perceived image on the retina.
