PHOTOACOUSTIC TRANSDUCER WITH OPTICAL FEEDBACK

摘要

A photoacoustic ultrasound transducer receives excitation light on a bundle of optical fibers. The optical fibers in the bundle are divided to direct the excitation light onto light bars positioned on either side of an imaging stack. A small portion of the optical fibers direct a portion of the excitation light onto an optical sensor that is located within the transducer housing.
