Abstract
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.
