摘要： An imaging apparatus (100; 200; 300) configured to image an object to be examined (115) is provided. The apparatus includes splitting means (122; 209; 305) configured to split light obtained by combining the returned light and the reference light into a plurality of lights having different polarization components; and detecting means (133, 134; 312, 313) configured to detect the plurality of lights. The apparatus further includes a correcting unit configured to correct a phase difference between different polarization components generated by an optical member provided on an optical path of the measurement light or an optical path of the reference light.

摘要： A polarization-sensitive OCT apparatus includes an interference unit configured to split light emitted from a light source into measurement light and reference light and to generate interfered light by causing returning light of the measurement light that has irradiated a subject to interfere with the reference light that has traveled through a reference arm, a splitting unit configured to split the interfered light into different polarization components, a generation unit configured to detect the polarization components split by the splitting unit and to generate a signal, detection units configured to detect respective polarization states of the measurement light in a sample arm, the returning light of the measurement light that has passed through the interference unit, and the reference light that has passed through the interference unit, and polarization control units configured to control the respective polarization states on the basis of the respective polarization states that have been detected.
