Method and apparatus for realtime-monitoring astronomical object with speckle interferometry |
摘要 |
A realtime monitor of an astronomical object such as a double star using speckle interferometry comprises a TV camera for picking up an image of a star which is formed by a telescope, first means for producing an incoherent still picture of the star on the basis of an output from the TV camea, second means for producing a power spectrum of the star by converting the incoherent still picture to a coherent image and then optically Fourier-transforming it, third means for adding the consecutively produced power spectra to obtain an average power spectrum, and fourth means for controlling first, second and third means and calculating a normalized average power spectrum of an object star through dividing the average power spectrum of the object star by that of a reference star.
