Study of 3D display information based on the mutual intension distribution of imaging light field

In accordance with the theory of partially coherent light, the correlation degree of light disturbance for all pairs of object points has been expounded and measured with their mutual intensity. Furthermore, the expression of mutual intensity distribution on the image plane by a set of prolate spheroidal wave functions has been given. Then, the number of freedom degree of light field on the image plane has been worked out illuminated by three light conditions, coherent, incoherent and partially coherent light. This approach provides a novel expression of 3D display information. (C) 2013 Elsevier GmbH. All rights reserved.
