MEASURING METHOD FOR SPR AND SYSTEM THEREOF

摘要

A measuring method for SPR and a system thereof are disclosed. Said method comprises: firstly a coherent broad-spectrum pulse light with linear polarization is irradiated on a surface of the SPR sample and a reflection occurs. Then said coherent broad-spectrum pulse light and/or said reflected light is monotonically chirped in the time domain. Finally, the SPR reflected light, which is monotonically chirped in time domain, is detected and a resonant wavelength information is obtained according to the detected signal.
