Optical image subtraction in fluorescein-doped boric acid glass.
The interference of two coherent images with a controlled phase difference between them is shown by using four-wave mixing in fluorescein-dye-doped boric acid glass and a liquid-crystal television spatial light modulator. We present results showing the digital optical exclusive OR operation with milliwatt optical power and an output that is compatible with CCD camera sensitivities.
