【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100~400m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 ord to solve that problem of poor real-time measurement of the high-spectral imaging system in the passive ranging of the oxygen-A absorption band, a multi-spectral non-imaging measurement method with an average transmittance of the oxygen A absorption band is proposed. The method uses three narrow-band filters to respectively collect the radiation intensity information of the target at the oxygen absorption band and the left and the right shoulder. The photoelectric conversion device was selected as the photoelectric conversion device, and the average transmittance of the oxygen-A absorption band was measured under the field condition. A line-by-line integral model of the transmittance of the oxygen A absorption band is established, and the feasibility of the method is verified by comparing the experimental measurement and the theoretical value of the model. The comparison results show that the measurement error of the average transmittance of the oxygen-A-absorption band is between 0.146% and 1.576% in the range of 100-400m, and the feasibility of the method is proved.
