    • The optical analysis system (1) is arranged to determine an amplitude of a principal component of an optical signal. The optical analysis system (1) comprises a first detector (5) for detecting the optical signal weighted by a first spectral weighting function, and a second detector (6) for detecting the optical signal weighted by a second spectral weighting function. For an improved signal-to-noise ratio, the optical analysis system (1) further comprises a dispersive element (2) for spectrally dispersing the optical signal, and a distribution element (4) for receiving the spectrally dispersed optical signal and for distributing a first part of the optical signal weighted by the first spectral weighting function to the first detector (5) and a second part of the optical signal weighted by the second spectral weighting function to the second detector (6). The spectroscopic analysis system (30) and the blood analysis system (40) each comprise an optical analysis system (1) according to the invention.
    • 光学分析系统(1)被布置成确定光信号的主分量的幅度。 光学分析系统(1)包括用于检测由第一光谱加权函数加权的光信号的第一检测器(5)和用于检测由第二光谱加权函数加权的光信号的第二检测器(6)。 为了提高信噪比,光学分析系统(1)还包括用于光谱分散光信号的色散元件(2)和用于接收光谱分散的光信号并用于分配光信号的分布元件(4) 由第一光谱加权函数加权到第一检测器(5)的光信号的第一部分和由第二光谱加权函数加权到第二检测器(6)的光信号的第二部分。 光谱分析系统(30)和血液分析系统(40)各自包括根据本发明的光学分析系统(1)。
