Patent ID: 7262895

Claim:
A method for determining a desired operating condition of an optical scanning oscillation device, the method comprising: (a) providing a mathematical model that relates oscillation frequencies to time intervals of the oscillation device, each oscillation frequency having an oscillation period and each individual time interval being less than its related oscillation period and corresponding to the time required for the oscillation device to move from a first scan angle position to a second scan angle position when the oscillation device is operating at the oscillation frequency that is related to the individual time interval; (b) establishing a drive frequency for a specific optical scanning oscillator; and (c) using the mathematical model and the drive frequency for the specific optical scanning oscillator to determine a target time interval for the specific optical scanning oscillator, the target time interval corresponding to a desired time interval for the specific optical scanning oscillator to move from the first scan angle position to the second scan angle position.
