摘要：
An optical monitoring system is provided for use with a blood processing system having a yoke that rotates an umbilicus about a rotational axis at a first speed, which causes rotation of an associated centrifuge at a second speed about the rotational axis that is different from the first speed. The system includes a light source configured to illuminate a disposable flow circuit received in the centrifuge and a light detector configured to receive an image of the disposable flow circuit to detect the location of an interface between separated blood compenents within the disposable flow circuit. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge and is configured to be in a fully operational mode for interface detection only when a transparent portion of the centrifuge is visible to the monitoring system.
