Abstract
A machine vision apparatus (24) and method are provided which allows imaging by or with the aid of artificial observation devices, such as video cameras, binoculars, telescopes, and other optical observation devices (10) which have an objective lens (12) passing light from an object or scene being viewed to a focal plane (18) at which is located a surface (22) which is at least partially reflective. Conventionally, such optical observation devices provide a retro-reflective light return into the scene being observed. Such a light return from an observation device can be detrimental, for example, to certain experimental results, or to the accuracy of machine vision (i.e., imaging) employed in robotic manufacturing tools.
