title: Blurred image recovery by a phase-processing method with tilt correction.
abstract: We present an improved method that incorporates tilt correction for blurred image recovery. A previously proposed method, which can compensate image blurring due to atmospheric turbulence, was improved to increase recovered image quality by correcting the tilt effect resulting from, e.g., a telescope's tracking jitter. Real-image analysis based on data from a 1.5 m diameter telescope with an infrared camera as well as from a computer simulation were performed. The results suggest that using the tilt-correction method yields an image quality that is much better than that obtained without the correction.
