An optical testing device for use in testing an optical measuring instrument provides incident light from a light source to an incident object and receives reflected light due to reflection of the incident light at the incident object. The optical testing device includes an incident light receiving section that receives incident light, and a light signal providing section. The light signal providing section provides a light signal to the incident object after a predetermined delay time since the incident light receiving section has received the incident light. A reflected light signal due to reflection of the light signal at the incident object is provided to the optical measuring instrument. The delay time is approximately equal to the time between emission of the incident light from the light source and reception of the reflected light by the optical measuring instrument in the case of actually using the optical measuring instrument.
An optical testing apparatus for use in testing an optical measuring instrument that provides incident light from a light source to an incident object and receives reflected light due to reflection of the incident light at the incident object, the optical testing apparatus comprising:
An optical testing method for testing an optical measuring instrument that provides incident light from a light source to an incident object and receives reflected light due to reflection of the incident light at the incident object and that has a light receiver, the optical testing method comprising:
