| 摘 要： | 为了对干涉光谱成像仪进行光谱定标,针对空间调制该仪器的原理,得出了其光程差和光谱分辨率的计算方法,并分析了仪器的线型函数.在实验中使用多种单色光源(波长范围:450～950 nm)和扩束准直镜(焦距120 mm、口径50 mm)进行光谱定标测试.结果表明:影响实验室光谱定标不确定度的主要因素为d/f的测量误差和标准光谱的误差. |

| Abstract: | Spatially Modulated Imaging Fourier Transform Spectrometer(SMIFTS)is an instrument depended on interference,which can obtain interferential information and achieve spectral information by fourier transform.Wavelength calibration is prerequisite for SMIFTS to obtain the spectrum information exactly.The way of extreme search that uses multi-lasers(wavelength range:450～950 nm)and collimating lens is carried out for the wavelength calibration of SMIFTS.Principle,method and result of the experiment are given then.The results indicate that the primary factors influencing lab wavelength calibration's precision are two reasons:measure precision of d/f and the precision of standard spectrum. |
| Keywords: | Wavelength calibration Fourier transform Uncertainty |
