- 振動子に駆動振動を励振し、この振動子に加わる回転角速度に基づいて前記振動子から出力される検出信号に基づいて回転角速度を測定する方法であって、
前記振動子に前記駆動振動を励振する自励発振回路を備えており、この自励発振回路が、リングオシレータおよび電流/電圧増幅器を備えており、このリングオシレータを用いて矩形波の起動信号を振動子に与え、前記振動子の出力信号を前記電流/電圧増幅器によって増幅しつつ前記自励発振回路内をループさせることで前記駆動振動を安定発振させることを特徴とする、回転角速度の測定方法。 - 振動子に駆動振動を励振し、この振動子に加わる回転角速度に基づいて前記振動子から出力される検出信号に基づいて回転角速度を測定する装置であって、
