The multiUVspectrums demo imaging system based on double spectrums linear UV detectors is developed, which is working at 250~280nm and 330~365nm. The system can obtain 1D panoramic images in the range from 0 to 360 degrees. The large relative aperture UV lens is designed which is optimized for two linear fields. Image acquisition & preprocessing circuits based on FPGA is also developed. At the last of the paper, the results of the imaging experiments are reported which are the first reports of the imaging results of the AlGaN UV sensors in China.
