MEASUREMENT APPARATUS AND MEASUREMENT METHOD |
| 摘要 |
A sensor unit photoelectrically converts received light to output image data. A lens unit condenses light reflected by an object surface to be measured on the sensor unit. A lens control unit controls a geometric condition of rays passing through the lens unit. The sensor unit and the lens control unit are controlled to acquire a multi-angular reflectance property in a neighborhood of a specular reflection direction of the object surface. |

1. A measurement apparatus comprising:
a sensor unit configured to photoelectrically convert received light to output image data; a lens unit configured to condense light reflected by an object surface to be measured on the sensor unit; a lens control unit configured to control a geometric condition of rays passing through the lens unit; and a measurement control unit configured to control the sensor unit and the lens control unit so as to acquire a multi-angular reflectance property in a neighborhood of a specular reflection direction of the object surface. |
