Abstract:
A method for operating an indicia reader such as a laser scanner is provided. The method affords a simplified technique for monitoring the offset between the drive frequency and the resonant oscillation frequency of the laser scanner. The phase offset between the drive frequency and the sense frequency is monitored to derive the drive frequency's offset from the resonant oscillation frequency.
