Remote light based angle sensing instrument

摘要

An instrument, for measuring and setting the angle between two work-pieces, that is placed on one of the work-pieces so that it projects two laser spots onto the second work-piece at which time a measurement is made of the distance along each of these laser axes which, combined with a known angle between the two axes allows the instrument to determine then display the angle between the two work-pieces allowing the user to read the angle and adjust the angle if needed.
