Imaging with Johnson-Nyquist noise Guevara Vasquez, Fernando
Description
We present a method for imaging the conductivity of a body by heating it in certain locations and measuring thermal noise currents at its boundary. The connection between thermal noise currents, temperature and the conductivity was discovered by Johnson and Nyquist in 1927 and relies on the Fluctuation Dissipation Theorem that we exploit here for imaging purposes. We show how the problem can be transformed into a well-known hybrid inverse problem and discuss possible applications.
