Abstract:

A method employing laser interferometry was used for detecting inhomogeneities of refraction index in optical glass prior to use in optical fabrication. A Twyman-Green interferometer configuration using a laser source was constructed. System errors were removed by a Moire technique. Samples of A, B, C and D glass were introduced into one of the beams and the resultant fringe patterns analyzed to obtain the magnitude of the index of refraction variations. Author
