Abstract
Official abstract text for this publication.
In order to change a size of an imaging area of a tomographic image of an object to be inspected easily, provided is an optical tomographic apparatus for acquiring a tomographic image of an object to be inspected, the optical tomographic apparatus including a control unit for controlling a measuring light path length changing unit to change an optical path length of measuring light in a case where the size of the imaging area of the tomographic image is changed, and for controlling a movable unit for moving a focus lens for focusing the measuring light to the object to be inspected along an optical path to move the focus lens in association with the change in the optical path length of the measuring light.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical tomographic apparatus configured to acquire a tomographic image of an object to be inspected based on light obtained by combining return light from the object to be inspected irradiated with measuring light with reference light corresponding to the measuring light, the optical tomographic apparatus comprising: a measuring light path length changing unit configured to change an optical path length of the measuring light; a movable unit configured…
