PURPOSE:To obtain a portable sensor which takes an accurate measurement by irradiating a body to be measured with light from plural light sources, receiving reflected light beams by plural photodetecting elements, and recognizing the shape of the body to be measured on the basis of their coordinates. CONSTITUTION:Light from a light emission part 24 is guided to a light source terminal element 18 through an optical fiber 32 to strike the body 22 to be measured as incident light A. Then, reflected light B is photodetected by a photodetecting element group 20 and converted photoelectrically. The shape, color, material, and surface state of the body 22 to be measured are detected by an information processing part 26 and a shape recognition part 28 on the basis of the converted electric signal. |
