Development of a side band modulation and electronic damping seismometer.
Main Article Content
Abstract
The Instrumentation Department of the Atmospheric Sciences Center has been developing a seismometer with optical displacement detection and side band modulation using LEDS and phototransistors matched at the near infrared wavelength, allowing the use of high electronic gains. An electronic damping system and a feedback method for positioning and correcting is used to optimize the seismometer characteristics.
