Claim:
1. A device, comprising: 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 configured to produce an optically interacted light when a sample light is sequentially transmitted through the at least two integrated computational elements, wherein, a first one of the at least two integrated computational elements comprises a first plurality of layers of material selected according to a linear regression vector associating the sample light with a sample characteristic via a first proportionality value, a second one of the at least two integrated computational elements comprises a second plurality of layers of material different from the first plurality of layers of material and selected according to the linear regression vector associating the sample light with the sample characteristic via a second proportionality value, and wherein the optically interacted light has an optical intensity; at least one detector arranged to receive the optically interacted light and generate a signal indicative of the optical intensity; and a processor that is configured to obtain from the signal indicative of the optical intensity a value of the sample characteristic.
