Optical Data Processing and Statistical Optics
Abstract
This final scientific report contains a summary of research at Caltech on the wavelength sensitivity of speckle. Included in this bibliography are research publications by N. George, A. Jain, A. Livanos, R.D.S. Melville, C. H. Papas, and J. Roth. Topics in speckle supported under the subject contract are described: (1) diffraction by a serrated aperture and (2) propagation in an experimental test chamber containing a turbulent gaseous mixture. Research on the fabrication of grating structures for use in integrated optics is also described. Chirped or variable period gratings have been successfully made by a holographic process. Briefly, a waveguiding layer of Corning 7059 glass is sputtered onto a substrate glass using the Technics MIM Model 5.5 ion-beam etching machine. Photoresist is coated onto the waveguiding layer, exposed holographically in an argon or helium-cadmium laser beam, developed and then ion-milled. Extensive theory and technique are reported in the bibliography of publications listed in this report.
