Research on 10.6μm Laser Disturbance to Infrared Detector System

Abstract

In order to research laser weapon soft damage to infrared missile, 10.6μm laser disturbance to infrared detector system was researched. First, 10.6μm laser atmospheric propagation transmittance was deduced. Laser atmospheric propagation transmittance relation curve was obtained. The relation curve is changed by atmospheric visibility and laser propagation distance. Then the experiment about on-axis laser disturbance to charge coupled device imaging detectors system was conducted. Charge coupled device saturation power density was measured. The relation curve between charge coupled device saturation area ratio and laser incident energy was obtained. Finally, 10.6μm laser energy which can disturb effectively infrared detector system was calculated. Some valuable data and conclusions were gained.
