摘要： A Micro Electronic Mechanical System (MEMS) scan controller generating clock frequency and a control method thereof are disclosed. The MEMS scan controller is for a MEMS mirror in a bi-direction laser scanning units (LSU). By detecting resonant frequency of the MEMS mirror, the scan controller sends frequency modulation signal and amplitude modulation signal of the MEMS mirror to a bridge circuit of the MEMS mirror for adjusting and stabilizing the MEMS mirror. A clock signal corresponding to the resonant frequency of the MEMS mirror at the moment is also sent so that scan data is sent within the effective scanning window in forward direction/reverse direction. Thus high-precision scanning is achieved.

摘要： A MEMS scan controller with inherent frequency and a method of control thereof applied to controllers of a MEMS mirror of bidirectional scanning laser printers are disclosed. The amplitude of the MEMS mirror is adjusted by using the inherent frequency so that scan data string is sent within effective scanning window with preset frequency of a laser source of the laser printer and a certain time interval. Thus the controller is simplified and the high precision scanning is achieved.
