    • A rotary spectrometer including a plurality of input ports. Each input port may be arranged to receive an optical waveguide carrying electromagnetic radiation. The spectrometer also includes a plurality of optical bandpass filters, which are housed on a first body that rotates under the control of a motor so that each optical bandpass filter may be brought into alignment with each input port. Further, the spectrometer includes a plurality of detector circuits disposed on a second body that rotates with the first body. Each detector circuit is optoelectrically coupled to one of the plurality of optical bandpass filters, thereby resulting in each detector circuit being dedicated to responding to a range of wavelengths determined by the bandpass filter to which it is optoelectrically coupled.
    • 一种包括多个输入端口的旋转光谱仪。 每个输入端口可被布置成接收携带电磁辐射的光波导。 光谱仪还包括多个光学带通滤光器,它们容纳在电动机控制下旋转的第一主体上,使得每个光学带通滤波器可以与每个输入端口对齐。 此外,光谱仪包括设置在与第一主体一起旋转的第二主体上的多个检测器电路。 每个检测器电路被光电耦合到多个光带通滤波器中的一个,从而导致每个检测器电路专用于响应由光电耦合到其的带通滤波器确定的波长范围。
