1. A detection apparatus comprising:

  • a housing comprising a sleeve, a front cover formed on a first end of the sleeve, and a rear cover positioned on an opposite second end of the sleeve, the front cover defining a light input hole;

    an image detection module comprising;

    a barrel received in the sleeve and apart from the sleeve, the barrel surrounding the light input hole;

    at least one lens received in the barrel; and

    an image sensor received in the barrel and configured to receive light from the at least one lens and generate a plurality of image signals;

    an ultrasonic detection module comprising;

    a piezoelectric member fixed to the housing and arranged between the barrel and the sleeve, the piezoelectric member is configured to emit a plurality of ultrasonic waves and receive the reflected ultrasonic waves; and

    an ultrasonic control module operable to apply a voltage on the piezoelectric member, receive the voltages generated by the piezoelectric member, and generate a plurality of voltage signals when receiving the voltages from the piezoelectric member;

    a circuit board received in the barrel, the image sensor positioned on the circuit board and facing the front cover, the ultrasonic control module positioned on the circuit board and facing the rear cover; and

    a connecting terminal electrically connected to the circuit board to output the image signals and the voltage signals, wherein the image sensor is electrically connected to the circuit board, and the ultrasonic control module is electrically connected to the piezoelectric member and the circuit board.
