Abstract : We investigated the feasibility of using uncooled infrared (IR) imagers in multispectral and wideband imaging for ground disturbance detection. Samples of sand, soil and mixture of both were used in the experiments. The multispectral imaging was carried out using IR bandpass filters. A software tool was used to process wideband and multispectral images to determine sample temperature contrast from which we examined effects due to reststrahlen features or other phenomena. A two-point, side-by- side scanning scheme showed possible ground disturbance detection by picking up substantial contrast when the two-point was entering and exiting the disturbed zone.
