Laser And Holographic Methods In The Inspection Of Flat Glass Plates

An inspection technique for optical instrument cover glasses based on laser and holographic interferometry has been developed. The method ensures high accuracy in determining the geometrical and optical characteristics of glass plates, claimed to be superior by a factor of 2-10 to that obtainable by conventional collimation.
