Bright field illumination

Most common technique for illuminating diffuse, non-refelctive objects.

This is the most common technique for illuminating diffuse, non-reflective objects. The term bright field refers to the mounting position of the illuminator. If a camera is positioned pointing towards a plain mirror, the bright field is the area in which any reflected light is within the FOV (field of view) of the camera.
