We present a theory of and a design for a new kind of optical computer employing a phase-conjugating resonator loaded with a volume-holographic recording medium. Coupled Mode equations are derived and solutions presented showing error-correcting content-addressable and associative memory. Multiple scattering in the volume enables the reconstruction of associative chains and cycles, permitting the sequential readout of time-sequences of images and the classifications of images into groups. Applications to invariant pattern recognition, goal seeking by optimization of a path product, and sentence disambiguation are discussed.
