As far as I am aware of the state of the art in the use of photorefractive material in biomedical applications, they can be used in acouto-optic imaging where photons are ultrasonically tagged.

Photorefractive crystals such as BSO are used in holographic detection of these tagged photons (e.g. http://www.opticsinfobase.org/ol/abstract.cfm?uri=ol-38-3-287). The interference between the recorded phenomenon and an off-axis reference beam is recorded on the crystal, and finally detected by a photodiode.

Some usefull papers about the use of photorefractive materials for biomedical application have been published by the Authors of the above mentionned paper and might be a usefull starting point for dealing with photorefractive holography.

Nicolas

Dear Nicolas,

Thank you very much for this information.

Very Sincerely,

Yuriy

Dear Yury! I have some experience in the use of photorefractive material as a biosensor, particularily in spectroscopy. You could be introduced with my paper published in JBO 9(4),820-827,2004. It's included into my RG profile.

Sincerely,

Alexander

Photorefractive materials are also use to image through scattering media (tissue) by phase conjugation. Look for D. Psaltis publications.

Dear Yuriy

We have published a paper on depth resolved holographic imaging of biological specimens (here, a rat tumor spheroid) using organic photorefractive materials. You can find the paper here

Dear Sebastian,

Your paper is very interesting. Do you have some latest results?

Best,

Kevin
