Abstract
Disclosed is a strain calculation method and system for phase-sensitive optical coherence elastography (PhS-OCE), including the following steps: obtaining interference spectra for various states during sample deformation, and extracting spectral information including multiple amplitude maps and multiple phase maps from these interference spectra. In the present disclosure, the speckle decorrelation phenomenon in PhS-OCE can be eliminated, the measurement range is expanded, and tangential displacement fields and strain fields can be measured by PhS-OCE technique while ensuring high axial sensitivity in strain measurement.
