| Abstract: | The principle of the weak DC electric field sensor based on the Michelson fiber-optic interferometric structure has been studied.A new transducer utilizing the nonlinear effect of the electrostrictive ceramics(e.g.PLZT) is proposed.The sensing system is experimentally implemented to overcome the l/f noise issue.The sensor has good linearity of response to the electric field. |
