【摘要】：為了解決氧氣A吸收帶被動測距中使用高光譜成像系統(tǒng)存在測量實時性差的問題,提出了一種氧氣A吸收帶平均透過率的多光譜非成像測量方法。該方法利用3個窄帶濾光片分別采集目標(biāo)位于氧氣A吸收帶及其左右?guī)Ъ绲妮椛鋸姸刃畔�。選擇光電倍增管作為光電轉(zhuǎn)換器件,在外場條件下開展氧氣A吸收帶平均透過率測量實驗。建立了氧氣A吸收帶透過率的逐線積分模型,通過對比實驗測量值與模型理論值驗證了該方法的可行性。對比結(jié)果表明,在測量距離為100~400m范圍內(nèi),氧氣A吸收帶平均透過率的測量誤差在0.146%~1.576%之間,證明了該方法的可行性。
[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.
