<p>This disclosure relates to a method and apparatus for measuring analyte concentration wherein radiometric readings are corrected for variations in the intensity of the illuminating radiation. The radiometer (40) and method provide for simultaneously illuminating both a target in the form of a test element (S) and a target in the form of a reference material (126), and for sequentially detecting radiation from the targets (S, 126). To provide for the detection of derived radiation from both of the targets (S, 126) generated as a result of the simultaneous illumination, one of the targets (S, 126) produces time-delayed derived radiation having an intensity that is a function of the intensity of the radiation used to simultaneously illuminate the targets (S, 126).</p> |
