The sampling theorem for deterministic functions is used to locate the center of gravity of a spectral line obtained by photon counting with a multichannel spectrometer. The sampling step and the width of the channels have been evaluated to locate the line with maximum accuracy. Our analysis and experimental results give the requirements needed of a photon counting multichannel Fabry-Perot spectrometer to improve the accuracy of measurement of the spectral interval between two lines.
确定性函数的采样定理用于确定通过多通道光谱仪进行光子计数所获得谱线的重心位置。已对采样步长和通道宽度进行了评估,以便以最高精度定位谱线。我们的分析和实验结果给出了光子计数多通道法布里 - 珀罗光谱仪为提高两条谱线之间光谱间隔测量精度所需满足的要求。
