Abstract

1384281 Diffraction gratings TRADE & INDUSTRY SECRETARY OF STATE FOR 10 May 1973 [16 March 1972] 12272/72 Heading G2J In forming diffraction gratings by interferometric methods, the original beam of coherent light from which the two interfering beams are produced in known manner, is passed through a rotating diffuser. By thus modifying the coherence of the light the effects of dust and optical aberrations is minimized.
