Abstract:
1. A sensor, comprising: a light source for producing at least one incident light field; a sensor chip, the sensor chip comprising: a detector device comprising a one-dimensional or two-dimensional array of detectors; and a wavelength scanning device located in a light field emitted from the light source to influence light emitted from the light source to yield the incident light field, or a wavelength scanning device located in the light field emitted from the waveguide grating structure to influence the light field emitted from the waveguide grating structure to yield an influenced emitted light field incident on the detector device, wherein the sensor detects a wavelength dependent signal as a function of a scanning wavelength set by the wavelength scanning device, and the wavelength dependent signal is indicative of the change of the effective index of refraction caused by the reaction of the sample with the at least one chemofunctional layer or biological cell.
