Under existing conditions, the use of optical lens, imaging spectrometer, and the establishment of a rectangular CMOS image sensor spectral imaging system. Wide spectrum of white LED illuminated sample, by ordinary optical imaging lens, then the multi-channel narrowband filter array on the image plane splitting, and finally by the CMOS image acquisition system, converting optical signals into electrical signals, and then converted by the analog-digital converter chip to a digital signal to the computer. Finally, computer-spectral image cube collected for processing. At the same time, the advantages of airborne multispectral imager used in the UAV trials, obtain higher picture quality, and maintain a portable, imaging speed, and further validate the reliability of the experimental system.
