摘要：
The present invention provides a single detector-based multifocal optical coherence tomography system comprising: a light source for generating a low-coherence ray of light； an optical isolator or an optical fiber circulator for protecting the light source； a first optical distributor； a second optical distributor； a third optical distributor； a sample arm configured such that a light ray for contrasting a surface portion and a light ray for contrasting a core portion, which are incident from the second optical distributor and the third optical distributor, respectively, are converted into parallel light by a collimator and pass through a polarizing distributor or are reflected thereby, and resulting polarized light for contrasting the surface portion, which has a horizontal or vertical component, and polarized light for contrasting the core portion, which has a component perpendicular to the polarized light for contrasting the surface portion, are used to obtain sample signals of the surface portion and the core portion, respectively； a reference arm having a plurality of polarizing distributors such that the light ray for contrasting the surface portion and the light ray for contrasting the core portion, which are incident from the second optical distributor and the third optical distributor, respectively, are converted into parallel light by the collimator and pass through the polarizing distributors or are reflected thereby, and resulting polarized light for surface portion referencing, which has a horizontal or vertical component, and polarized light for core portion referencing, which has a component perpendicular to the polarized light for surface portion referencing, are used to obtain reference signals reflected by reference reflecting mirrors provided in positions corresponding to those of the surface portion and the core portion, respectively； a spectrometer for converting interference signals into image signals； and a computer for realizing images from t
