Abstract
Systems and methods are provided for determining and controlling the location of an interface between separated fluid components within a channel of a centrifugal separation chamber being rotated about a rotational axis. Light from a light source is received by a collimator, which directs collimated light through the channel in a direction substantially parallel to the rotational axis. At least a portion of the collimated light exiting the channel is received by a light detector configured as a photodetector array. A signal emitted by the light detector is received by a controller, which determines the location of an interface between separated fluid components within the channel based at least in part on the signal. When the controller determines that the interface is not at a target location within the channel, the controller controls a centrifugal separator and/or a pump system to move the interface to the target location.
