Application of an exclusively binarized correlation-calculation method to wind velocity measurement by use of stellar scintillation patterns

An exclusively binarized method for the correlation calculation of image pr ocessing is presented with application to velocity measurements. The exclus ively binarized correlation-calculation method is capable of determining th e peak position of the correlation even with a small number of random-patte rn images. Because the velocity is deduced from the movement of the correla tion-peak position within a time interval, the method is suitable for the v elocity measurement of random patterns. The method is applied to the measur ement of the upper-atmospheric wind velocity by use of stellar scintillatio n patterns. (C) 2001 Optical Society of America.
