Patent abstract
A device and method for monitoring a light beam (e.g., laser beam) without intruding upon the light beam is disclosed. The device comprises a focusing lens which receives scattered light from a reflective or transmitting optical element and directs the scattered light to a photo detector. The photo detector generates one or more electrical signals which are proportional to an intensity distribution of the light beam for analysis by a processor. The analyzed electrical signals are then used to adjust a light beam source accordingly. The device may further comprise a display and printer for visually depicting the light beam characteristics.
