Dispersion-eliminated coded-aperture light field imaging using digital micromirror devices

In this paper, we report a dispersion-eliminated coded-aperture light field (DECALF) imaging system based on digital micromirror devices. Using a dual-DMD design to compensate for dispersion in the entire visible spectrum, the DECALF imaging system captures 1280 x 1024 x 5 x 5 (x,y,theta,phi) color light field images at 20 Hz. Using three-dimensional (3D) color scenes, we experimentally demonstrate multi-perspective viewing and digital refocusing by DECALF imaging system.
