摘要
In an examination head used in an apparatus for examining periodontal disease, measuring light beams, which are parallel light beams, are emitted from a light-emitting surface of a light-emitting member. A reflecting member on which a reflecting surface is formed is provided at a position opposing the light-emitting surface of the light-emitting member. With a tooth and gum sandwiched by the light-emitting surface and reflecting surface, the measuring light beams to are emitted. Interference signals are generated utilizing light beams which are a reflection of the measuring light beams to from the reflecting surface in addition to light beams which are a reflection of the measuring light beams to from the tooth and gum. Interference signals having an excellent S/N ratio are obtained.
