Abstract
A memristor element is used to create a spectrally programmable optical computing device for use in, for example, a downhole environment. An electromagnetic field is applied across the memristor element in order to alter its spectral properties. In turn, the spectral properties of sample-interacted light optically interacting with the memristor element are also altered. This alteration in spectral properties allows the memristor to be “programmed” to achieve a variety of transmission/reflection/absorption functions.

A spectrally programmable optical computing device, comprising:
- electromagnetic radiation that optically interacts with a sample to produce a sample-interacted light;
- a memristor element comprising a spectrally alterable material, the memristor element being positioned to optically interact with the sample-interacted light to produce optically-interacted light which corresponds to a characteristic of the sample;
- an electromagnetic field produced across the memristor element to alter the spectrally alterable material, thereby altering a spectral property of the electromagnetic radiation to produce the optically-interacted light;
- and
- a detector positioned to measure the optically-interacted light and generate a signal,
- wherein the signal is utilized to determine the characteristic of the sample.
