Abstract
An abnormality detection apparatus, which detects abnormality of a resonant sensor signal output from a sensor unit of an optical deflector, includes: a resonant sensor signal processing unit including a function of A/D-converting the resonant sensor signal output from the sensor unit into resonant sensor signal data, and a function of outputting a data acquisition completion and the A/D-converted resonant sensor signal data; a resonant sensor signal predicted-data calculation unit configured to calculate predicted data on the resonant sensor signal; and a resonant sensor signal abnormality determination unit configured, in a case where the mirror portion is in a resonant state, to compare the predicted data on the resonant sensor signal with actual resonant sensor signal data, and to detect abnormality of the resonant sensor signal based on a result of the comparison.
