Abstract
Arrangements for detecting the presence of an opaque object in an area, such as a person in a robotic work cell. Multiple light sources, light reflecting surfaces, light boxes with hole patterns or fiber optic light sources are spaced around the perimeter of the area and imaged by a camera. The change of the camera signal from its normal condition is used to interrupt power to safeguard personnel and/or machinery.
