Abstract
An imaging system for sensing light in an area of high optical contrast is disclosed. In some implementations, the imaging system is for monitoring a welding operation, whereby a photochromic filter is used to reduce the intensity of the light observed from the welding arc. The imaging system includes a light source whereby light from the light source activates the photochromic filter. Thus, the opacity of the photochromic filter depends on the intensity of the light from the light source.
