Abstract
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.
