Abstract:
In an opto-electronic device utilizing a band of light for quantitative analysis of a specimen containing a target molecule, the opto-electronic device comprising a specimen cell adapted for receiving the specimen and for transporting the band of light, a device for comparing the band of light before entering the specimen with the band of light after exiting the specimen, the device for comparing comprising:an optical sensor; and, a signal processor for determining a quantitative level of the target molecule within the specimen; wherein the signal processor utilizes Bayes's Theorem for determining the quantitative level of the target molecule within the specimen and a probability density of interest is estimated as PR(c|I), is estimated as PR(c|I)=âˆ«d&agr;P(c&agr;|DI), where c is the concentration of the target molecule conditioned on data D and any prior information I, and the probability density for parameters c, &agr; conditioned on data D is P&it;(c&it;â€ƒ&it;Î±|DI)=P&it;(D|c&it;â€ƒ&it;Î±&it;â€ƒ&it;I)&it;P&it;(c&it;â€ƒ&it;Î±|I)P&it;(D|I),whereP(D|c&agr;I)=Likelihood Function, P(c&agr;|I)=Prior Probability Density, P(D|I)=Probability Density for D.
