Jones matrix oct system and program for carrying out image processing on measured data obtained by said oct

A computer readable no-transitory medium storing a program installed in a computer of a Jones matrix OCT system to generate tomographic images of a measuring target based on spectral interference beams detected by an optical detector, where the Jones matrix OCT system has:

• a wavelength-scanning light source;
• a coupler that splits a light from the wavelength-scanning light source into two optical paths;
• a reference arm provided along one of the two optical paths, to reflect one split light using a reference mirror and thus generate reference light;
• a probe arm provided along the other of the two optical paths, to irradiate and reflect the other split light onto the measuring target and thus generate object light;
• a polarization-separation detection unit that superimposes the reference light and object light to generate spectral interference beams and then detects the spectral interference beams using optical detectors;
• and a computer;
• wherein the probe arm has a polarization delay unit that linearly polarizes the other light and then splits it into S-wave component and P-wave component, where the S-wave component and P-wave component are superimposed with each other through optical paths of different optical path lengths, respectively;
• the polarization-separation detection unit can obtain four spectral interference signals by using the optical detectors to detect the different spectral interference beams in a depth direction of the measuring target that correspond to the S-wave component and P-wave component, respectively, among the vertically polarized components of the spectral interference beams, as well as the different spectral interference beams in the depth direction of the measuring target that correspond to the S-wave component and P-wave component, respectively, among the horizontally polarized components;
• and
• the program is characterized in that it allows the computer to function as an image-processing means that can generate different tomographic images in the depth z direction of the measuring target from the four spectral interference signals, and can also generate tomographic images of higher resolution by obtaining coherent coupling from a matrix of the four spectral interference signals and by also obtaining coherent elements that have been combined after de-randomizing phases of the four spectral interference signals.
