PROBLEM TO BE SOLVED: To precisely detect a change in a refractive index of an analyte. SOLUTION: An SPR sensor is illuminated over a wavelength range where an incident signal exists. Intensity of a reflected signal from the SPR sensor is detected with a wavelength discrimination characteristic imparted to the incident signal or the reflected signal. The wavelength discrimination characteristic is imparted in a tuning rate preliminarily assigned within the wavelength range. Then, the detected intensity is sampled at a sampling rate, and an intensity profile related to the SPR sensor is generated from the sampling in a wavelength resolution determined by the tuning rate and a sampling rate.
