3D image sensing and reconstruction with time-domain multiplexed computational integral imaging (CII)

We present a method to compute high-resolution three-dimensional (3-D) images based on integral imaging. A sequence of integral images (II's) is captured by a time-domain multiplexing method. For the acquisition of each II the location of the lenslet array is shifted in a plane perpendicular to the optical axis. The sequence obtained this way is digitally processed with a super-resolution reconstruction (SR) algorithm to obtain a reconstructed image, appropriate to a viewing direction that has a spatial resolution beyond the optical limitation.
