Assignee: RICOH COMPANY, LTD.
Field: Optics (Instruments)
Classification: CPC G  A | IPC G

Claim 12:
13. A optical device comprising:
a light source configured to irradiate an object with light;
a detector having a photo-sensing surface, the detector configured to receive the light reflected by the object and detect a position of the reflected light on the photo-sensing surface thereof;
circuitry configured to
output data of a degree of inclination of the object obtained based on the position of the light on the photo-sensing surface of the detector and a prescribed parameter, and
change the prescribed parameter based on the position of the light on the photo-sensing surface of the detector; and
a storage unit configured to store a plurality of detection values of the position of the light on the photo-sensing surface of the detector,
wherein the circuitry is configured to change the prescribed parameter based on a distribution of the plurality of detection values on the photo-sensing surface of the detector.
