PROBLEM TO BE SOLVED: To provide a method of monitoring and controlling the processing of blood and blood samples, specifically, the separation of blood into its components. SOLUTION: An optical method and a device are provided for measuring two-dimensional distribution of transmitted light intensity, scattered light intensity or both from a separation chamber of a centrifugal separator. In one embodiment, the measured light intensity comprises an image of a separation chamber or its component, such as, an optical cell of the separation chamber. In another embodiment, a multifunctional monitoring and control system is provided for blood processing. A feedback control system is provided for measuring and processing the two-dimensional distribution of the light intensity, in real time, so as to be used as the basis of output signals for controlling blood processing. The optical cell is provided for monitoring and controlling blood processing. COPYRIGHT: (C)2009,JPO&INPIT
