Paper Abstract
To obtain the averaged Fourier power spectrum of a time-varying stellar speckle images from a binary star a portable real-time Fourier-transform processor is developed for stellar speckle interferometry, in which the Fourier transform of the image is done optically by using a microchannel spatial light modulator. Several double star images are analyzed on the telescope sites by the real-time processor. The cycle time of 2-10 Hz is achieved in this instrument depending upon incoming light level.
