1. a kind of for obtaining the compact optical spectrometer system of the spectrum of sample, comprising:

  • Fluorescence detector, for detecting the light issued from the sample, wherein the light is by being irradiated to the sampleIt is generated;

    Optical light filter, between the sample and the detector, the optical light filter includes to have cardiac wave in differenceLong multiple sub- optical filters, wherein the optical light filter is configured to provide the spectrum of angular coding;

    The diffusing globe being installed between the sample and the optical light filter;

    AndFirst Fourier transform concentrating element, is installed between the optical light filter and the fluorescence detector, wherein byThe first Fourier transform concentrating element converts to its space encoding the light;

    Wherein the Compact spectrum instrument system does not contain any dispersive optical elements.
