Abstract:

In this paper,we propose a real-time monitoring system for multi-channel fiber optic surface plasmon resonance (SPR) spectral imaging.With the use of i HR 550spectrometer equipped with Synapse CCD (area array charge-coupled device,1024×256pixels),we can get the spectral data of multiple independent channels while keeping the advantage of a mono-channel SPR sensor based on the full resonance curve measurement.A real-time monitoring system for the control of iHR550spectrometer,Synapse CCD data processing and SPR data processi ng is developed based on LabVIEW.
