発明の名称 (英語) JONES MATRIX OCT SYSTEM AND PROGRAM FOR CARRYING OUT IMAGE PROCESSING ON MEASURED DATA OBTAINED BY SAID OCT
発明の概要(英語) The present invention achieves Jones matrix OCT having improved image stability and image quality and an improved image depth region. Light from a wavelength scanning light source (6) is divided into two light paths. A reference arm (12) is provided in one of the light paths, and a probe arm (13) that generates object light by irradiating light onto an object under measurement and causing the light to be reflected is provided in the other light path. The probe arm (13) is provided with a polarization delay unit (21) for linearly polarizing the light, subsequently dividing the light into an S-wave component and a P-wave component, passing the S-wave component and P-wave component through light paths having different light path lengths, and superimposing the components. Photodetectors (68, 70) detect different spectral interference light in the depth direction of the object under measurement corresponding to the S-wave component and P-wave component of the spectral interference light corresponding to a vertically polarized component and a horizontally polarized component and obtain four spectral interference signals.
