Abstract

Stellar specklegrams at different wavelengths are examined. The position of the brightest speckle at one wavelength is shown to coincide nearly with that at a widely separated wavelength. The shift-and-add operation for specklegrams at one wavelength produces a high-resolution stellar image at the other wavelength. We show that the shift-and-add operation at 450 nm results in a high-resolution image at 800 nm by use of observational speckle data from which specklegrams at these wavelengths are taken simultaneously.
