Abstract

Optical computing devices are disclosed. One exemplary optical computing device includes an electromagnetic radiation source configured to optically interact with a sample and at least two integrated computational elements. The at least two integrated computational elements may be configured to produce optically interacted light, and at least one of the at least two integrated computational elements may be configured to be disassociated with a characteristic of the sample. The optical computing device further includes a first detector arranged to receive the optically interacted light from the at least two integrated computational elements and thereby generate a first signal corresponding to the characteristic of the sample.
