The triple correlation - Applications in astronomical speckle interferometry and in signal processing
Abstract
The concept of the triple correlation in image and signal processing is presented. Its advantages are illustrated using the example of imaging through the earth's turbulent atmosphere. Problem-oriented formulas for this example are given. Various other applications of the triple correlation and the bispectral Fourier analog are discussed, including the Gamos triple intensity interferometer, bispectral Satos velocity measurements, bispectral holography, bispectral detection of nonlinearities, shift-invariant imaging in extremely weak light intensity, and higher-order spectrograms of musical tones.
