Resolution-enhanced integral imaging microscopy that uses lens array shifting

A resolution-enhanced integral imaging microscope that uses lens array shifting is proposed in this study. The lens shift method maintains the same field of view of the reconstructed orthographic view images with increased spatial density. In this study, multiple sets of the elemental images were captured with horizontal and vertical shifts of the micro lens array and combined together to form a single set of the elemental images. From the combined elemental images, orthographic view images and depth slice images of the microscopic specimen were generated with enhanced resolution. (C) 2009 Optical Society of America
