  • The most important working mode of HXMT (Hard X-ray Modulation Telescope) is scanning mode, which includes all-sky imaging survey mode and small region scanning mode. The standard imaging analysis requires complete data of two dimensional observations in the region of interest. By using the information of space modulation and rotating modulation contained in the observed data simultaneously, quick-look imaging can obtain the intensity distribution with data of one dimensional observation. Thus quick-look imaging can obtain the image of a region soon after HXMT scan through it. The technique of HXMT quick-look imaging is described in this paper in detail. And later in this paper the distribution of sensitivity and locating accuracy of HXMT quick-look are analyzed based on numeric simulation. The quick-look imaging can improve the sensitivity of HXMT for transient sources, discover and locate high energy bursts in the FOV of HXMT, reduce the disturbance of transient sources and bursts to the standard imaging. It will be an important supplement to the standard imaging analysis.
