ABSTRACT:
The invention relates to a system and method for monitoring light using a photosensitive mast mounted on a support or machine. A light signal, such as a laser, is detected by the photosensitive mast which has a plurality of optical fibers distributed longitudinally along and completely around the mast. The optical fibers are of lengths which differ by very small amounts, thereby creating any desired resolution of the photosensitive mast. The optical fibers are connected to a collecting device for gathering the light signals and determining the position of the light measuring device relative to the rotating laser light source.
