Real-time image subtraction and addition are realized by phase conjugation in an erythrosin- B-doped-polyvinyl alcohol film. In a degenerate four-wave mixing configuration, two mutually cross-polarized phase conjugate waves are generated: one is the phase conjugate wave by means of the degenerate four-wave mixing process, while the other is that of the holographic component by means of photo-induced irreversible chemical process. The image subtraction or addition can be performed by interference between two phase conjugate waves through an analyzer.
