Abstract
A laser for producing a beam of radiation which is then refined in cross sectional dimension by use of plano-cylindrical lenses. The refined beam of radiation falls incident on a part to be measured. The unobstructed portion of the beam is then bifurcated by a pair of reflective surfaces which produce non-parallel radiating beams; each beam comprised of the unobstructed portion of radiation-which has passed radially opposed halves of the part. The magnitude of radiation present in each non-parallel radiating beam is then measured.
