An optical testing apparatus is used in testing an optical measuring instrument that provides incident light from a light source to an incident object and receives reflected light of the incident light at the incident object. The apparatus includes an incident light receiving section, a light signal providing section, an imaging section, and an optical axis misalignment deriving section. The incident light receiving section receives incident light. The light signal providing section provides a light signal to an incident object after a predetermined delay time since the incident light receiving section has received the incident light. The imaging section images the incident light. The optical axis misalignment deriving section derives misalignment of the optical axis of the incident light with respect to the incident light receiving section based on misalignment between the incident light receiving section and the imaging section as well as an imaging result with the imaging section.
An optical testing apparatus used in testing an optical measuring instrument that provides incident light from a light source to an incident object and receives reflected light as a result of reflection of the incident light at the incident object, the optical testing apparatus comprising:
