摘要：
A photoacoustic imaging system is disclosed that includes an ergodic relay coupled optically to a light source configured to produce a light pulse and further coupled acoustically to a transducer. The ergodic relay is further configured to direct at least two PA signals to the transducer. Each of the at least two PA signals are produced at different positions within the field of view of the object to be imaged in response to illumination by a single light pulse. The transducer detects each of the at least two PA signals after each of at least two delays that correspond to the position at which each PA signal was produced.
