Quantitative detection and evaluation system for dazzling effect of non-lethal laser dazzlers
A set of quantitative detection and evaluation systems were developed to measure and evaluate the dazzling effect of a non-lethal laser dazzler. The developed systems use non-biological quantitative testing methods, designing a target composed of a simulated human eye optical system, a retina simulator, and a simulated eyeball support device. Through it, the detection system can capture the original laser dazzling image using a human-like effect, combined with the CIE general disability glare equation of biological characteristics. After software processing, the bionic dazzling image can be comprehensively analyzed, and the dazzling effect can be obtained. For the level judgment, the spectral resolution of the system is 1 nm, the working band is 380–780 nm, the ambient light test range is 1×10-4–1×103 lx, and the testable maximum power density threshold is 2 mW/cm2. At present, the system has carried out numerous verification tests comparing the dazzling effect for volunteers and has been applied to the dazzling effect test of a series of police laser dazzlers. It has provided support for the selection of anti-terrorism anti-riot equipment, with several evaluation tests conducted. The verification tests and practical applications show that the system further solves the problem of using non-biological means to quantitatively test the physiological effects of laser dazzling and facilitates a scientific evaluation of the dazzling effect of non-lethal laser dazzling devices. The studies on the dazzling effect of the eyepiece provide an adequate experimental research base.
