摘要: 为了防止FTIR光谱仪在车载运动过程中产生的振动对光谱仪造成不良影响,保证光谱仪的信噪比及测量精度,采用角镜式干涉仪结构与单自由度减振系统相结合的FTIR光谱仪系统来提高仪器抗振性能。对FTIR光谱仪系统进行了几组桌面振动测试实验,验证了角镜式结构具有一定抗振性能,其中单自由度减振系统对系统抗振性能有明显提高。最后,进行FTIR光谱仪系统车载实验,得出运动中测量的光谱平均信噪比达到静止过程中平均信噪比的94%,结果表明整机系统能够很好的在移动平台上平稳运行,具有良好抗振性,为光谱仪的车载运行检测提供应用条件。

Abstract: In order to prevent the negative effect of vibration produced by vehicle-mounted FTIR spectrometer in the process of movement on the FTIR spectrometer,and to ensure signal to noise rate and measurement accuracy of spectrometer,a FTIR spectrometer system combining structure of angle mirror and damping system with single degree of freedom was designed to increase the anti-vibration performance of spectrometer.A series of testing experiments about desktop vibration were conducted to validate the good anti-vibration performance of structure of swing angle mirror,which also proved that damping system of single degree of freedom could significantly increase the anti-vibration performance of spectrometer.Finally,A experiment on vehicle-mounted FTIR spectrometer was conducted and showed that the mean signal to noise rate of measured spectrum in the process of movement reached 94 percentage of the mean signal to noise rate in the static process,which indicated that the designed system was able to run smoothly in mobile platform,have good anti-vibration performance and provide application condition for vehicle-mounted FTIR spectrometer monitoring.

Key words: Fourier transform infrared spectrometer, angle mirror, single degree of freedom damping system, vibration resistance, signal-to-noise ratio
