Combining with the moving target in the field, the smoke pot is used for the efficiency test of the smoke extinction and screening in the field. The smoke extinction model is modified and verified by the data acquisition from the multi-spectra imaging sensor. The obtained experimental data are analyzed and compared with the calculation method of the smoke classical theory, and the experimental principle is obtained and proved to meet the engineering experience value. The measurement data about the visible sensor, mid-wave infrared sensor, long wave imaging sensor and laser power meter are collected during the field test, which provides the basis for the smoke application and the imaging sensor efficiency.
