Abstract

We report full-field depth-resolved holographic imaging through scattering media by use of a photorefractive polymer device in the near infrared. Real-time images through seven scattering mean free paths are acquired in a few seconds with a broadband superluminescent diode at 794 nm. A depth resolution of 15 microm and a transverse resolution of better than 42 microm are achieved. The photorefractive devices used are based on a poly(N-vinylcarbazole):2,4,7-trinitro-9-fluorenone dimalenitrile charge-transport network doped with the electro-optic chromophore 1-(2'-ethylhexyloxy)-2,5-dimethyl-4-(4"-nitrophenylazo)benzene.
