Zusammenfassung:	An actuator includes an oscillating unit including two or more oscillation circuits each configured to output an oscillation signal including a frequency, which is changed in response to movement of a detection target, a frequency down-converting unit configured to down-convert frequencies of two or more oscillation signals respectively output from the two or more oscillation circuits, and a determining unit configured to calculate a position of the detection target in response to two or more down-converted oscillation signals output from the frequency down-converting unit.
