Abstract
The diffraction image of an incoherent bright annular test object is obtained by using Fourier-Hankel transform method. The effect of longitudinal sinusoidal vibrations has been studied and results are given in graphical form for various sizes of the object. It is observed that in certain cases the presence of vibrations completely distorts the object. Hence a detailed analysis of image intensity distribution should prove useful in aerial reconnaissance work and performance evaluation tests.
