Photorefractive polymers with high diffraction efficiency in the
visible and near-infrared regions of the electromagnetic spectrum have
been developed. These polymers, which have a large dynamic range
because of their high orientational birefringence, incorporate a dye
designed to have a large dipole moment and a high linear polarizability
anisotropy. Such polymers have enabled demonstrations of imaging
through scattering media, using a holographic time-gating technique at
a wavelength that is compatible with the transparency of biological
tissues and with the emission of low-cost semiconductor laser diodes.
