PROBLEM TO BE SOLVED: To provide an apparatus for optical tomography, whose driving mechanism is simplified and which can maintain a polarization state without moving a measuring light source.SOLUTION: An apparatus for optical tomography acquires a tomographic image of an object to be inspected, based on light obtained by multiplexing: a light returned from the object that is irradiated with a measuring light through a scanning part; and a reference light that corresponds to the measuring light. The apparatus has: a dividing part for dividing a light emitted from a light source into the measuring light and the reference light; and a focusing part arranged between the dividing part and the scanning part in an optical path of the measuring light. |
