PV型HgCdTe光电探测器中的混沌及其诊断
Chaos and its diagnosis in PV-type HgCdTe detector
摘要
对激光辐照半导体光电探测器的实验研究,发现当一束不太强的稳定连续波激光照射在PV型HgCdTe光电探测器上时,可以引起探测器出现混沌行为.利用光电探测器的光电压信号随时间变化的实验数据,通过求功率谱、计算Lyapunov指数对混沌进行了诊断.
Abstract
In our experimental research on laser irradiating semiconductor photodetectors, chaos in the PVtype HgCdTe detectors irradiated by a mild stable continuous wave laser is found. The detectors will give chaotic output when the irradiation power density of laser increases above the saturation threshold of them. Chaos is diagnosed by determining the power spectrum and Lyapunov exponent from the output signal of the detectors in this paper.
