Optical-analytical devices with capacitance-based nanomaterial detectors

摘要

Optical computing devices may include capacitance-based nanomaterial detectors. For example, an optical computing device may include: a light source that emits electromagnetic radiation into an optical system that extends from the light source to a capacitance-based nanomaterial detector; a material disposed in the optical system for optically interacting with the electromagnetic radiation and producing light with optical interaction; and the capacitance-based nanomaterial detector comprising one or more nano-sized materials configured to have an absorption spectrum that has been tuned to resonance and configured to receive the light with optical interaction, a vector corresponding to the characteristic of interest Relationship is to apply to the light with optical interaction using the absorption spectrum, which has been subjected to a resonance tuning, and to generate an output signal indicating the characteristic of interest.
