Abstract：
The imaging test setup for the Hard X-ray Modulation Telescope (HXMT) mission was built to give verification of detector performance and the imaging properties of HXMT. It consists of 18 slat-collimated NaI(Tl)/CsI(Na) phoswich detectors with a total collective area of 5000cm². Several experiments were implemented with radioactive sources 15m away from the detector plane. We obtained a point-source location accuracy of 2' and an angular resolution of $<$5' using direct demodulation method.
