An apparatus, and method of operating the same, detects changes in biomass accumulating on a surface of a substrate while minimizing bulk effect. The apparatus includes a sensor substrate and two illumination sources. A first illumination source generates a first light having a first central wavelength. A second illumination source generates a second light having a second central wavelength different than the first wavelength. The first and second light are mixed to produce a combined light. An analyte solution is introduced to the sensor substrate. Incident light of the combined light is reflected from the sensor substrate to produce a signal. The signal is imaged with a camera to obtain a reflectance. Reflectance produced by the combined light is not affected by variations in the dielectric properties of the analyte solution. A biomass accumulated on the substrate is computed based on the reflectance.

An approximation B′f(Id,λ) of a fluorescence spectral emissivity coefficient by a standard illumination light Id is obtained at following steps from spectral power distributions R(Ik,λ) of sample radiation lights radiated from a fluorescence whitened sample when the fluorescence whitened sample is sequentially illuminated with a plurality of excitation lights Ik having different spectral power distributions, and a spectral power distribution Id(λ) of the standard illumination light Id.
