Fiber optic applications on the Century-Detroit laser interferometer gages
Technical Report

OSTI ID:5331506
The application of fiber optics on the Century-Detroit laser inspection gages is investigated. The effects of directing the laser beam into the gagehead interferometer by fiber optics, and using fiber optics to transmit the interference fringe signal from the interferometer to the photodetectors are examined. Both incoherent (non-image-transmitting) and coherent (image-transmitting) optical bundles are tested. Results of these tests showed that neither the imaging nor the non-imaging fiber optic cables can be used to carry the laser beam into the gageheads. However, either type of cable can be used successfully to transmit the created fringe pattern to the photodetectors.
