Paper Abstract

The building block method provides a promising algorithm to reconstruct an astronomical object image from its bispectrum. While the building block method has been well applied on stellar objects, in the present study we examine the applications to extended objects such as planets and satellites. We have obtained the visible light specklegrams of Io (a Jupiter's satellite) at 515nm using the 2m telescope in Nishi-Harima Astronomical Observatory. We report a preliminary imaging result of Io using the building block method. The result is compared with the image as previously restored by the shift-and-add method with a deconvolution post-processing.
