The winner of the Rudolf Kingslake Medal and Prize for 1979 is Dr. J. R. Fienup of the Environmental Research Institute of Michigan. His award-winning paper on "Space Object Imaging through the Turbulent Atmosphere" appeared in Optical Engineering 18(5), 529 (1979). This work, begun with his 1975 thesis work at Stanford, developed in several papers prior to this one, and was summarized by him in Optical Engineering 19(3), 297 (1980). Fienup showed that an iterative computer process can reconstruct an object scene from a noisy record of the modulus of its Fourier transform. Since speckle interferometry can be used to derive a diffraction-limited modulus of the Fourier transform, application of Fienup's analysis to the retrieval of diffraction-limited images in speckle interferometry proved quite promising.
