Paper Abstract

In this paper, we present the continuous wavelet analysis for extract the information of photoacoutical signal sampled with a focoused transducer. The results demonstrate that wavelet transform of photoacoustic signals with 1 time averaging could reconstruct the localization and the size of absorbers, and it greatly reduced the data acquisition time. In addition, the results indicate that the localization and the size of absorbers could be recovered as the value of signal-to-noise ratio (SNR) is in the range from 0.3 to1.
