Based on the analysis and the comparison of stress pattern analysis by thermal emission (SPATE) and remote sensing rock mechanics (RSRM), the idea to detect the transient process of solid impact with thermal infrared (TIR) imaging technology is introduced. By means of TVS-8100MKII TIR imaging system, which has high recording speed, high space distinguishability and high temperature sensibility, TIR imaging experiments on free falling steel ball impacting on marble, granite, concrete, steel, organic-glass and wood plate are conducted. It was discovered that: (i) the target’s TIR temperature increases remarkably after impact; (ii) when ball’s size is not changed, the variation amplitude of target’s TIR temperature proportionally increases with the ball’s potential energy or falling height; (iii) the variation amplitude of target’s TIR temperature is involved with the material type and the surface glabrous condition of the target, and the amplitudes are in order as concrete, unpolished marble, steel plate, Based on the analysis and the comparison of stress pattern analysis by thermal emission (SPATE) and remote sensing rock mechanics (RSRM), the idea to detect the transient process of solid impact with thermal infrared (TIR) ​​imaging technology introduced.
