【摘要】 甚长波红外传感器响应光谱测量的过程中,探测器以及前置放大器均工作于线性工作区是必要的,否则由傅里叶变换光谱仪(FTIR)测得的响应光谱,在某些情况下仪器信号会发生饱和,从而引起响应光谱畸变,直接影响测试结果以及后续的分析工作。文中对利用FTIR测量光电探测器响应光谱时,光谱仪信号的饱和问题进行研究,改进了常规测试方法,提高了测试准确度。更多还原

【Abstract】 In measuring of long wavelength infrared device response,it is necessary that the sensor and preamplifier work in linearity. When using Fourier transform spectrometer (FTIR) to measure the sensor response, the spectrum signal will saturate if the sensor and preamplifier working in non-linearity, resulting in the spectrum distortion and wrong analysis result. The signal saturation is investigated. The measurement precision is increased by using the mathod.更多还原
