Scanner assembly and scanning oscillating mirror control method

The invention discloses a scanner assembly and a scanning oscillating mirror control method. The scanner assembly comprises a motor which is connected with a scanning oscillating mirror and a control circuit board and is further used for driving the scanning oscillating mirror to a required position according to driving signals of the motor; a scanning oscillating mirror for oscillating under the control of the motor and reflecting spot light source lasers emitted by a spot light source laser to a photoelectric position sensor; the spot light source laser arranged at the non-imaging surface, i.e., the back-surface direction of the scanning oscillating mirror; the photoelectric position sensor arranged at the non-imaging surface, i.e., the back-surface direction, of the scanning oscillating mirror; the control circuit board connected with the motor and the photoelectric position sensor; and a bandpass filter connected with the control circuit board and the motor.
