Abstract
A sorting flow cytometer receives a current alignment of a light beam, determines a difference between the current alignment of the light beam and a target alignment of the light beam, and calculates one or more voltage values based on the difference between the current alignment and the target alignment. The sorting flow cytometer uses the voltage values to adjust a position of at least one of a first alignment actuator extending in a first axial direction and a second alignment actuator extending in a axial second direction to reduce the difference between the current alignment of the light beam and the target alignment of the light beam.
