    摘要: An optical sensor includes a light emitter configured to irradiate a surface of an object with a plurality of non-parallel light beams, a light detector configured to detect a plurality of light beams that have been reflected within the object and have returned to the surface from a plurality of directions, a recording unit configured to store pre-calculated results of a plurality of models having different optical properties and physical structures, and a calculating unit configured to calculate a light amount ratio of the plurality of reflected light beams, and estimate an optical property of the object based on the calculated light amount ratio and the pre-calculated results.
