摘    要:为平衡光栅色散型光谱仪光通量、系统信噪比和光谱分辨率之间的矛盾,介绍了一种基于微狭缝阵列的静态双增益阿达玛光谱仪.在分析其实现静态双增益工作原理的基础上,阐述了由于阿达玛编码模板多狭缝阵列引起的光谱重叠的原因.为实现静态双增益阿达玛光谱仪光谱重叠校正,理论推导了光谱偏移量与阿达玛编码模板狭缝空间位置之间的关系,以及分光后某波长空间错位量与码元(狭缝)空间位置、波长之间的关系.仿真实验验证了此方法简单有效,无需复杂计算,修正速度快,易于编程实现.

Abstract:To obtain both high sensitivity and high throughput when measuring at the same time, a static double-gain Hadamard spectrometer is introduced, based on micro-slit array. The principle and instrument structure of static double-gain Hadamard spectrometer are described, and spectra aliasing caused by Hadamard encoding mask is investigated. The relationship between spectral offset and the spatial offset of incident slit is obtained. For a given wavelength spectrum, the spatial offset caused by the spatial offset of incident slit is also calculated in theory. The simulation results show that this method has no complex computation, with fast correction, and is easy in program realization.
Keywords:Spectrometer  Hadamard transform  Slit array  Spectra aliasing
