    摘要： An image acquisition apparatus irradiates light from a light source to an inspection object, obtains a tomographic image of the inspection object on the basis of a combined beam obtained by combining a return beam from the inspection object due to the irradiated light and a reference beam corresponding to the light, and obtains a plane image of the inspection object on the basis of the return beam from the inspection object due to the irradiated light. The apparatus performs a first scanning process to main-scan the irradiated light when the tomographic image is obtained, performs a second scanning process to main-scan the irradiated light at a speed higher than that in the first scanning process when the plane image is obtained, and performs a third scanning process to sub-scan the irradiated light when each of the tomographic image and the plane image is obtained.

    摘要： An optical tomographic imaging method is provided in which light from a light source is split into a measuring beam and a reference beam, the measuring beam being moved by a scanning optical system and guided to an object to be examined, the reference beam being guided to a reference mirror, and in which a tomogram of the object is generated from a return beam of the measuring beam reflected or scattered by the object and the reference beam reflected by the reference mirror. The method includes acquiring longitudinal sectional information on the object, calculating depth-position information on the object from the longitudinal sectional information, and acquiring a three-dimensional surface image of the object by controlling a reference-path length defined by the reference mirror and a scanning operation of the scanning optical system in accordance with the depth-position information on the object.
