Paper Abstract

We demonstrate a coherence gating system to image through turbid media by using photorefractive holography with ultrashort pulses. Sub-100 micrometers depth-resolved images of 3D objects embedded in a scattering medium have been obtained. Using a long integration time in Rhodium-doped Barium Titanate, an image of a test chart has been obtained through 16 mean free paths of scattering medium. Real-time depth- resolved imaging through 13 mean free paths of scattering medium has been demonstrated using a fast response time photorefractive multiple quantum well device. We will discuss the trade-offs and limitations of these photorefractive media for this application.
