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.
我们报告了利用近红外光折变聚合物器件通过散射介质进行全场深度分辨全息成像。使用794nm的宽带超发光二极管，在几秒钟内获取了穿过七个散射平均自由程的实时图像。实现了15微米的深度分辨率和优于42微米的横向分辨率。所使用的光折变器件基于掺杂了电光发色团1-(2'-乙基己氧基)-2,5-二甲基-4-(4"-硝基苯基偶氮)苯的聚(N-乙烯基咔唑):2,4,7-三硝基-9-芴酮二马来腈电荷传输网络。
