Abstract:
1. A handheld characteristic analyzer, comprising: a portable housing; at least one optical computing device arranged within the portable housing for monitoring a sample, the at least one optical computing device having at least one integrated computational element configured to optically interact with the sample and thereby generate optically interacted light; at least one detector arranged to receive the optically interacted light and generate an output signal corresponding to a characteristic of the sample; and a signal processor communicably coupled to the at least one detector for receiving the output signal, the signal processor being configured to determine the characteristic of the sample and provide a resulting output signal indicative of the characteristic of the sample, wherein the integrated computational element comprises a plurality of alternating layers of two materials, each of the plurality of alternating layers of two materials having a thickness selected to form an amplitude of the optically interacted light proportional to a vector product of a loaded regression vector and an input light beam.
