AI Technical Summary
In photoacoustic microscopy, due to the laser pulse instability and the delay in the response of electronic devices, the time when the detector receives the photoacoustic signal is inaccurate, and a time jitter effect occurs, affecting the axial positioning accuracy of the three-dimensional reconstruction image.
Using an unsupervised learning framework, unsupervised training is obtained by obtaining the original photoacoustic signal, signal offset parameters are determined, and time jitter correction is used to correct the original photoacoustic signal to obtain a high-precision target photoacoustic signal.
It effectively improves the accuracy of photoacoustic microscopy signal sampling, improves the imaging resolution, and meets the needs of high-precision imaging without improving the hardware of the photoacoustic microscopy imaging system or performing model training.
