Abstract

Conventional integral imaging systems utilize lenslet arrays with fixed focal lengths and aperture sizes. In this paper, we propose a time-multiplexed integral imaging method to enhance both the depth of focus and the resolution of a three-dimensional image by displaying it using an array of lenslets with different focal lengths and aperture sizes. The non-uniform lenslet parameters (focal lengths and aperture sizes) for our method are calculated. Our theoretical analysis indicates that significant improvements in both depth of focus and resolution can be obtained using the proposed technique. To the best of our knowledge, this is a first report on developing integral imaging systems using lenslets with non-uniform focal lengths and aperture sizes.
