Descripción
Phase diversity techniques actually provide robust post-processing
methods to restore solar images degraded by seeing-optical aberrations.
We present preliminary results of the application of a Partitioned
Phase-Diverse Speckle (PPDS) technique at THEMIS. The images have been
acquired using the IPM broad-band CCD camera and reduced using a
suitable IDL code. The spectral analysis of unrestored/restored images
shows a significant improvement of image quality, achieving diffraction
limited resolution.
