1 July 1990Machine vision quantification of internal S-distortion in fused fiber optics
The use of machine vision equipment to quantify internal optical aberrations
has recently proven to be effective for the inspection of fused fiberoptic
components . The fundamental benefits of this approach to dimensional inspection
are improved accuracy , repeatability and speed , in conjunction with automatic
data collection and statistical analysis . Recently revised specifications and
supporting calculations governing the optical distortion limits of an imaged
straight line across an 18mm clear aperture of a fiberoptic component have made
the current measurement method using an optical comparator both cumbersome and
unreliable. Requirements for inspection and certification of the maximum
deviation , warranting measurement on nunrous axes across the optic , further
illustrate the benefits of the vision inspection system. This discussion will
concentrate on vision equinent , optical techniques and referenced patterns
incorporated in the measurement of S-distortion to the new specifications in
fused fiberoptic inverters.
