    摘要： Light emitted from a light source is formed into parallel light beams, the parallel light beams are divided into two light beams, and one of the divided light beams is converted by a conical lens to light (beam) having an energy density on an optical axis maximized over a distance, and is applied to a surface of a measuring object, with another one of the divided light beams being applied to a reference mirror, so that, by detecting an interfered light beam between rearward scattered light of the light (beam) applied to the surface of the measuring object and reflected light from the reference mirror, a shape of the measuring object is measured.
