Abstract
A servo accelerometer includes a pendulum, a coil, a detection unit, and a servo unit. The detection unit has a photopotentiometer for receiving light passing through a slit of the pendulum and outputting a detection output on the basis of a change in resistance corresponding to a change in irradiation point. The servo unit has a displacement detection circuit for outputting a difference between a detection output from the photopotentiometer and a set value as a detection displacement amount.
