摘要： Stabilize phases by eliminating, without adding any expensive, complex hardware, the jitter between the wavelength scanning of a light source of SS-OCT and the timing of collecting the scan data with the light detector as spectral interference signals. A computer 16, which generates tomographic images based on the spectral interference signals detected by a light detector 15 from overlaid reference light emitted by a swept-source type light source 2 of the SS-OCT, split, and then reflected by a fixed reference mirror 8 on one hand and object light reflected by an object to be measured 6 on the other, is caused to function to apply rough correction using a first correction means and then apply detailed correction using a second correction means, to stabilize the phases of the SS-OCT.

摘要： A Jones matrix OCT is realized, which offers improved image stability, image quality, and depth range of image. The light from a wavelength-scanning light source 6 is split into two optical paths, and a reference arm 12 is provided along one optical path, while a probe arm 13 that irradiates and reflects light onto the measuring target to generate object light is provided along the other optical path, wherein the probe arm 13 has a polarization delay unit 21 that linearly polarizes the light and then splits it into S-wave component and P-wave component, where the S-wave component and P-wave component are superimposed through optical paths of different optical path lengths, respectively, after which optical detectors 68, 70 are used to detect different spectral interference beams in the depth direction of the measuring target corresponding to the vertically polarized component and horizontally polarized component, which respectively correspond to the S-wave component and P-wave component, to obtain four spectral interference signals.
