title: Picosecond optical correlation using dynamic holography in polyacetylene.
abstract: An image-processing system based on four-wave mixing in a film of polyacetylene less than 100 nm thick is demonstrated with a 1-ps processing cycle time. Image phase conjugation and cross correlation are performed with a resolution space-bandwidth product of 0.68 x 10(5) (equivalent to 261 x 261 pixels) in the phase-conjugate image. The light source was amplified optical pulses from a colliding-pulse mode-locked dye laser at a wavelength of 625 nm.
