Abstract:
The present invention provides a surface plasmon resonance (SPR) detection system and method. This system utilizes a detection light path to form a detection image containing incident angle information and wavelength information. During testing, full-spectrum scan is performed first to obtain a resonance wavelength of a sample. Then, partial-spectrum scanning is performed by continuously tracking the resonance wavelength, and the number of scanning points in each scanning cycle is controlled according to specific situation to shorten the scanning time, thereby obtaining the resonance wavelength of the sample in real time. When the refractive index of the sample changes, the corresponding resonance wavelength changes as well; by obtaining the change of the resonance wavelength, variation of the reflective index of the sample is calculated, which is rapid SPR detection of wavelength modulation.

Claim (Index 5):
An SPR detection method, comprising the following steps:\n (1) parallel scanning and recording a two-dimensional image of a sensing chip of a corresponding wavelength in an equal step size manner on the whole working spectrum segment; (2) obtaining a resonance wavelength of a corresponding sensing position according to the two-dimensional image and the pixel corresponding to the image; (3) obtaining a maximum resonance wavelength and a minimum resonance wavelength in all the resonance wavelengths; (4) obtaining a wavelength upper limit of a next-scanning region after moving the maximum resonance wavelength toward a long wavelength direction by a first distance, obtaining a wavelength lower limit of the next-scanning region after moving the minimum resonance wavelength toward a short wavelength direction by a second distance, and obtaining a next-scanning wavelength range according to the wavelength upper limit and the wavelength lower limit; (5) determining a scanning step size; (6) within the next-scanning wavelength range, rapidly scanning a partial-spectrum region according to the scanning step size determined in step (5) and recording a two-dimensional image corresponding to the scanning spectrum; (7) repeatedly performing steps (2)\u02dc(6) on the partial-scanning image to obtain resonance wavelengths of all the sensing positions at different times and obtain a two-dimensional wavelength-sensitive SPR sensing image.
