Detector with catch and release mechanism

A detector comprising:

• a vibration mechanism including a first mechanical vibrator vibrating in at least a first direction, a second mechanical vibrator mechanically connected to the first mechanical vibrator vibrating in at least a second direction perpendicular to the first direction, and a catch and release mechanism configured to catch the first mechanical vibrator in vibration and release the caught first mechanical vibrator to start vibration of the first mechanical vibrator;
• a first circuit configured to detect a first position of the first mechanical vibrator in accordance with the first direction and output a first signal corresponding to the detected first position, the first signal including a first frequency;
• a second circuit configured to detect a second position of the second mechanical vibrator in accordance with the second direction and output a second signal corresponding to the detected second position;
• a detection circuit configured to detect the second signal by using the first signal as a reference of synchronous detection and output a detection signal;
• a filter configured to continue on a moving average process on the detection signal according to a clock signal for a period set based on the first signal;
• and
• a first controller circuitry configured to control the vibration mechanism to cause the first mechanical vibrator to start vibrating in the first direction by the catch and release mechanism in synchronization with the clock signal and continue the started vibration by the catch and release mechanism for the period during which the filter performs the moving average process.
