Non-spectroscopic sensing enabled by an electro-optical reservoir computer (2022)
Journal Article
Anufriev, G., Furniss, D., Farries, M., & Phang, S. (2022). Non-spectroscopic sensing enabled by an electro-optical reservoir computer. Optical Materials Express, 12(5), 1767-1783. https://doi.org/10.1364/OME.449036

A fully bio-inspired apparatus to perform non-spectroscopic sensing to discriminate and determine the constituent concentrations of a chemical mixture is proposed. Here, fully bio-inspired means that it is comprised of a biomimetic sensor and a neuro... Read More about Non-spectroscopic sensing enabled by an electro-optical reservoir computer.
