Improving the Angular Resolution of Coded-Mask Telescopes by Direct Demodulation

Zong-Jun Shen, Jian-Feng Zhou


We develop a new procedure to improve the angular resolution of coded-mask telescopes by the Direct Demodulation Method (DDM). DDM has been applied to both real and simulated data of INTEGRAL/IBIS. The angular resolution of IBIS/ISGRI has been improved from about 13' to 2'.
