Abstract :
In this paper, we briefly review our work on low-coherence photorefractive holography and report on the current state of the art. We present what is, to the best of our knowledge, the fastest-ever three-dimensional (3-D) imaging system and present results obtained with imaging at 470 frames/s (fps). We demonstrate the versatility of photorefractive holography using various sources, including LEDs, high-power diode arrays, and a novel, all solid-state broad-band laser. We present preliminary results obtained by combining the technique of structured illumination with photorefractive holography for the first time. We demonstrate that this novel holographic optical sectioning technique may be implemented for both reflection and fluorescence imaging
