Abstract
Techniques and arrangements that utilize speckle imaging and autocorrelation to estimate the PSF of an image sensor for a digital imaging apparatus, e.g., a camera or a scanner. In particular, a system of components described herein is a simple arrangement that does not require a complex setup. Therefore, the system is portable and easy to set up. Additionally, by utilizing autocorrelation, the calculations of PSF using data obtained by the system are simplified.
