تأثیر فرآیند وانت در عمق میدان نمایش تصویری انتگرال

A typical integral imaging (InIm) display consists of the pickup process and the display process. In the InIm display process, the facet braiding phenomenon influences on the depth of field (DOF). Actually, the DOF of the InIm system not only depends on the the facet braiding in the display process, but also seriously depends on the pickup process. Only the pickuped object within the certain region can capture clear elemental images, and blurry elemental images could be attained outside the region. The region that can be recorded clear elemental images is called the pickup DOF of InIm, which influences on the total DOF of the InIm display. The pickup DOF calculation formula of InIm is presented, which is compared with the DOF caused by facet braiding. Experimental results agree with the theoretical analysis, which is benificial for designing the InIm display system.
