Abstract

High resolution reconstruction of complicated objects from incomplete and noisy data can be achieved by solving observational modulation equations or correlated modulation equations iteratively under physical constraints. Simulations and experiments show that wide field and high resolution images of space hard X-rays and soft γ-rays can be obtained by scan observation of a collimated non-position-sensitive detector.
