Abstract

A method and system for vibration correction in an oscillator. The method includes sensing vibrations along one or more axes via at least one accelerometer mounted on the oscillator, determining corrective factors based on an acceleration signal received from the at least one accelerometer by referencing a look-up table; and controlling the oscillator based on at least the corrective factors.

Claims

1. A method for vibration correction in an oscillator, the method comprising:

sensing vibrations along one or more axes via at least one accelerometer mounted on the oscillator;

determining corrective factors based on an acceleration signal received from the at least one accelerometer by referencing a look-up table; and

controlling the oscillator based on at least the corrective factors.
