    摘要:

    介绍了一种工作于1 355~1 555 nm的新型多通道短波红外光谱组件,并以理论和实验相结合的方式定量研究了入射角度对光谱组件各通道中心波长的影响.实验结果表明,在0~10°斜入射条件下光谱组件各通道中心波长呈现不同程度的短波方向偏移现象,偏移程度与入射角度呈正相关.分别绘制出理论和实验中心波长偏移曲线,实验发现在入射角为5°和10°时中心波长平均偏移幅度约为5.7 nm和18.67 nm.此外,参照实验得出的角度偏移曲线对两次不同入射角度条件下的光谱进行插值整合,成功地将光谱组件分辨率从7.5 nm提高到3 nm;在此实验基础上提出了通过改变入射角度发展一种多通道角度调谐光谱组件,进而利用此方法提高光谱组件的测试分辨率.该结论对后续设计光谱组件入射光学系统和提高光谱组件测试分辨率具有一定指导意义.

    Abstract:

    A novel short infrared multichannel integrated spectrum assembly ( MISA) worked in the range of 1 355 ~ 1 555 nm is reported. The influence of the incident angle on the center wavelength of each channel and the resolution of MISA is quantitatively studied in a theoretical and experimental manner.The experimental results show that the center wavelength of each channel of the spectroscopy component exhibits different degrees of short-wave direction shifting at 0 ~ 10° oblique incidence, and the degree of deviation is positively correlated with the incident angle. The theoretical and experimental center wavelength offset curves are plotted, and the experimental results show that the average shift amplitudes of the center wavelength at the incident angles of 5° and 10° are approximately 5. 7 nm and18. 67 nm, respectively. In addition, by referring to the experimental angle deviation curve, the spectrum was interpolated and integrated at two different incident angles, and the resolution of the spectral components was successfully increased from 7. 5 nm to 3 nm. Based on this experiment, we proposed a multi-channel angular tuning spectral assembly by changing the incident angle, and then using this method to improve the test resolution of the spectral components. This conclusion has certain guiding significance for designing the incident optical system and improving the test resolution of MISA.
