Abstract

In this paper, we proposed an optical balance using a Michelson Interferometer structure. The frequency of the interference signal is changed nonlinearly related with a weight to be measured, and this frequency change is processed by a processor to give a measured weight. Several measurements were performed and the good results were obtained with the fluctuation of about 1g.
