A method includes accessing a plurality of acceleration values generated by an inertial measurement unit of an optical system. The method includes identifying a maximum acceleration value (the accessed acceleration value having the greatest absolute value), identifying one or more adjacent acceleration values (the accessed acceleration value adjacent in time to the maximum acceleration value), and identifying a nearest adjacent acceleration value (the adjacent acceleration value having the value nearest the maximum acceleration value). The method includes determining a corrected peak acceleration. The corrected peak acceleration is the sum of a first value corresponding to an average of the maximum acceleration value and the nearest adjacent acceleration value and a second value corresponding to the product of a correction value and the difference between the maximum acceleration value and the nearest adjacent acceleration value. The method includes determining whether the corrected acceleration value exceeds a predefined threshold acceleration value.
