Paper Abstract

A fiber optic electrometer with oscillating element is described in this paper. The non-contact interferometric interrogation system of electrometer provides high-sensitivity measurement of voltage and charge, inducing very small disturbances in the measured object. The sensitivity of 2 (DOT) 10-4 V/(Hz)1/2 was achieved, while the sensitivity of 3 (mu) V/(Hz)1/2 is predicted from the thermal fluctuation limit. An order of magnitude estimation indicates that the sensitivity to an electric charge close to the electron charge may be achieved with an electrometer of considered type.
