Optical wavelength transform continuous in time, time shift, and scale Conference Paper uri icon


  • 1994 COPYRIGHT SPIE. A continuously-evolving, nonstationary time signal is essentially impossible to analyze digitally. To analyze it by analog optics, we suggest an acoustooptic wavelet transform continuous in separation time, clock time, and frequency. For convenience, we cause the pattern for any signal feature to remain spatially fixed while that feature is in the time window.
