SYSTEM FOR ILLUMINATING AND IMAGING AN OBJECT WITH A SPECULAR REFLECTING SURFACE

摘要

A system for illuminating and imaging an object with a specular reflecting surface, including a reflector and an imaging-receiving device. The reflector provides substantially uniform diffusivity and substantially uniform reflectance of the light from an illumination source, and defines an aperture. The image-receiving device is located with a particular position behind the aperture of the reflector, and the aperture is sized with a particular dimension, such that the narcissus effect of the system is reduced to a single point and the object with the specular reflecting surface can be imaged with high accuracy.
