Abstract
A method and system are presented for use in determination of the concentration of an analyte in a subject's medium. The medium is irradiated with at least two radiation components to produce detectable radiation responses of the medium thereto. These at least two radiation components are selected to have different mean wavelengths and such that the spectral bandwidth of at least one of said at least two radiation components is characterized by relatively high variability of the extinction coefficient of the analyte of interest across said spectral bandwidth. This enables analysis of data indicative of detected radiation responses of the medium to said at least two radiation components and determination of the concentration of said analyte.
