摘要
为了解决氧气A吸收带被动测距中使用高光谱成像系统存在测量实时性差的问题,提出了一种氧气A吸收带平均透过率的多光谱非成像测量方法。该方法利用3个窄带滤光片分别采集目标位于氧气A吸收带及其左右带肩的辐射强度信息。选择光电倍增管作为光电转换器件,在外场条件下开展氧气A吸收带平均透过率测量实验。建立了氧气A吸收带透过率的逐线积分模型,通过对比实验测量值与模型理论值验证了该方法的可行性。对比结果表明,在测量距离为100~400 m范围内,氧气A吸收带平均透过率的测量误差在0.146%~1.576%之间,证明了该方法的可行性。
Abstract
In order to solve the problem of the poor real-time measurement caused by a hyperspectral imaging system in passive ranging based on oxygen A absorption band, a method of multi-spectral non-imaging measurement for the average transmission of oxygen A absorption band is proposed. In this method, the radiation intensity information of targets located in oxygen A absorption band and its left and right band shoulders is collected by three narrow band filters. Experiments are carried out to measure the average transmission of oxygen A absorption band in the external field, and a photomultiplier tube is used as the photoelectric converter. A line-by-line integral model for oxygen A absorption band transmission is built, and the feasibility of the proposed method is verified when we compare the experimental results with the theoretical results. The contrast results show that the measurement error of oxygen A absorption band average transmission is from 0.146% to 1.576% within the range of 100-400 m, which proves the feasibility of the proposed method.
