OPTICAL INTERFERENCE TOMOGRAPH

摘要

An optical interference tomograph in which a thick (or thin) part of an examinee can be grasped intuitively when a "position-layer thickness" graph is displayed from two-dimensional or three-dimensional tomographic information on the examinee. In the optical interference tomograph, layer thickness at each position on a scanning line is calculated for at least one of layers constituting the examinee according to two-dimensional tomographic information on the examinee which is obtained, for example by scanning the surface thereof with irradiation light. Subsequently, an axial line indicating a position on the scanning line is displayed in a shape similar to that of the scanning line and the calculated layer thickness is plotted with a predetermined scale from the axial line in the direction normal to the axial line.
