A novel cataluminescence(CTL)sensor array was constructed with 3types of nano-materials,and the CTL profiles of ten toners were obtained.The work suggested that different toner's CTL profiles on the same nano-material surface were different while the same kind of toner's CTL profiles on different nano-materials surfaces were also different.By using dynamic time warping(DTW)to calculate the distance between the test and the standard CTL profiles,exhibiting the DTW distance in a threedimensional coordinate sy...
