OPTICAL WAVELET-MATCHED FILTERING WITH BACTERIORHODOPSIN FILMS

We present here the experimental and numerical results to demonstrate the superior performance of optical wavelet-matched filtering over con ventional matched filtering. For this purpose, the biomolecule materia l bacteriorhodopsin (bR) as the recording media and the improved dual- axis joint transform correlator configuration as the preferred optical setup have been used. Compared with the dual-axis joint Fourier trans form correlator, the dual-axis joint wavelet transform correlator prov ides better correlation performance. (C) 1997 Optical Society of Ameri ca.
