Wavelet Signal Processing for Resolution Enhancement in a Recurrence Tracking Microscope

详细

Based on continuous wavelet transform (CWT), we show that the resolution of a recurrence tracking microscope (RTM) is enhanced to subnanometer scale. Our approach helps us to read information on frequency bands, time of revivals, and corresponding time of fractional revivals more accurately. We demonstrate that wavelet analysis provides a deeper information on the phenomena of quantum recurrences in general. Our analytical results show very good agreement with numerical results based on experimental parameters.
