Optimisation of filters for optical correlation of noisy images

1999
The capacity of an optical correlator to identify, recognise and locate a target object in a cluttered scene depends greatly upon the qualities of the spatial filter it uses to represent the reference image. Noise in the input scene degrades the discriminative powers of correlators in the several optical configurations that have been proposed and ...

IV Triple-Correlation Imaging in Optical Astronomy

1991
Publisher Summary This chapter discusses the triple-correlation imaging in optical astronomy. The chapter discusses the high-resolution imaging methods of speckle masking (bispectrum or triple correlation processing), speckle spectroscopy, and optical long-baseline interferometry with arrays of large telescopes.
