  • MEMS scan controller with inherent frequency and method of control thereof
    Patent number: 7924486
    Abstract: 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.
    Type: Grant
