Abstract

This study proposed the new approach to gain sensitivity of sensors. Usually, noise sources are considered to reduce for gaining sensitivity or dynamic range. In practical system, it is not the case that the noise can be reduced. In this study, therefore noises are positively utilized to enhance the sensitivity of sensors, which improves the sensor system by means of stochastic method. In this paper, a change of optical path length in interferometer was measured by using CCD camera as a multi-sensor in order to check the feasibility of this method.
