Claim:
1. An optical image measuring apparatus comprising: an optical system including a scanner configured to change an irradiation position of signal light on an object and a focus position changer configured to change focus position of the signal light, and configured to detect interference light of returned light of the respective signal light from the object and reference light; an image forming part included within at least one processor including circuitry and configured to form a cross-sectional image based on detection results of a plurality of interference light corresponding to a plurality of irradiation positions of the signal light; a programmed controller configured to control the optical system to irradiate the signal light onto the plurality of irradiation positions repeatedly while changing the focus position; a composite-cross-sectional-image forming part included within the at least one processor including circuitry and configured to form one composite cross-sectional image based on two or more cross-sectional images formed by the image forming part on the basis of results of repetitive irradiation of the signal light, wherein the programmed controller is further configured to change the focus position continuously when the repetitive irradiation of the signal light is performed, and the composite-cross-sectional-image forming part is further configured to form the one composite cross-sectional image based on a parallelogram-shaped partial image including an image region corresponding to a corresponding focus position in each cross-sectional image.
