The present application provides an optical fiber-typed spectral confocal coherence tomography optical system and an application thereof. The system includes an optical fiber coupler, a broadband light source, a reference component, a sample component and a spectrometer. The reference component is connected to a first output end of the optical fiber coupler, for receiving a light source signal emitted by the optical fiber coupler and controllably forming the light source signal into an interference signal. The sample component is connected to a second output end of the optical fiber coupler, for receiving the light source signal emitted by the optical fiber coupler and forming a spectral confocal signal after the light source signal passes through a sample to be tested. The spectrometer is connected to a third output end of the optical fiber coupler.

Optical fiber-typed spectral confocal coherence tomography optical system and application thereof

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.
