Hi, You can refer to "Design and Noise consideration of an accelerometer employing modulated integrative differential optical sensing", Sensors and Actuators 84 (2000), pp. 53-64.

Thank you for your help. _______________________________________________ MEMS-talk@memsnet.org mailing list: to unsubscribe or change your list options, visit http://www.memsnet.org/mailman/listinfo/mems-talk Hosted by the MEMS Exchange, providers of MEMS processing services.
