| 摘 要： | 本文描述了用旋转调制器对天空X、γ射线源成象并兼测能谱的方法。它可以对大视场内的天空源测定位置、大小和强度。与常规准直器相比,它显示出多种优点。在硬X、γ射线波段,它不仅能对天空源成象,而且能测量其能谱和较强的谱线。

| Abstract: | A method for imaging celestial X-ray or gamma-ray sources with a rotating modulator is described. It can measure the locations, dimensions and intensities of the sources. Advantages of the rotating modulator over convertional collimators are discussed. It can also measure the spectra and lines of celestial hard X-ray and gamma-ray sources. |
