Real-time holographic image correction using bacteriorhodopsin

We present experimental results of one-way coherent imaging through a thin phase-aberrating medium using a holographic technique with bacteriorhodopsin as a real-time holographic material. Bacteriorhodopsin is well suited for the application when the aberration is time varying because of its real-time writing and erasing characteristics, sensitivity, and spatial resolution. We show results with final image resolution of greater than 20 line pairs/mm and high signal-to-noise ratio using a polarizationholcgraphy approach.
