Recently we proposed frequency division multiplexed imaging (FDMI), which allows capturing multiple images in a single shot through spatial modulation and frequency domain filtering. This is achieved by spatially modulating the images so that different images or sub-exposures are placed at different locations in the Fourier domain. As long as there is no overlap of the individual bands, we can recover different components by band-pass filtering the multiplexed image. In this paper, we present a Texas Instruments DMD based implementation of FDMI. An image is formed on the DMD chip; pixels are modulated by the micro-mirrors; and the modulated image is captured by a camera. By applying modulation during a sub-exposure period, the corresponding sub-exposure image is at the end recovered from the full-exposure image. Such a system could be used in a variety of applications, such as motion analysis and image deblurring. We will provide experimental results with the setup, and discuss possible applications as well as limitations. © 2014 SPIE.
