Abstract
A system includes a first optical sensor sensitive to both a parameter of interest, Parameter1, and at least one confounding parameter, Parameter2 and a second optical sensor sensitive only to the confounding parameter. Measurement circuitry measures Min response to light scattered by the first optical sensor, where M=value of Parameter1+K*value of Parameter2. The measurement circuitry also measures Min response to light scattered by the second optical sensor, where M=value of Parameter2. Compensation circuitry determines a compensation factor, K, for the confounding parameter based on measurements of Mand Mtaken over multiple load/unload cycles or over one or more thermal cycles. The compensation factor is used to determine the parameter of interest.
