Abstract
In this paper, we describe frequency division multiplexed imaging (FDMI), where multiple images are captured simultaneously in a single shot and can later be extracted from the multiplexed image. This is achieved by spatially modulating the images so that they are placed at different locations in the Fourier domain. The technique assumes that the images are band-limited and they are placed at non-overlapping frequency regions through the modulation process. The FDMI technique can be used for extracting sub-exposure information and in applications where multiple cameras or captures are needed, such as high-dynamic-range and stereo imaging. We present experimental results to illustrate the FDMI idea.
