Paper Abstract

Our goal was to use the technical accomplishments of the L.S.O.C.S., notably in spectros-copy of modulation in the applications undertaken in the applied optics department of this laboratory. Our efforts aimed at elaborating a system permitting us to optically compare with precision different objects. Since the problems becomes more complicated with the complexity of the form of the object, above all in the domain of curved shapes, the study of a comparator of gauge blocks was the first stage of the program. We hope that many of those who are presently using an older system of measurement will benefit from this one, which will be commercialized shortly.
