Abstract
A photoacoustic imaging device is suitable for performing photoacoustic imaging on an object to be tested and includes a light emitting device and a light-transmissible ultrasonic transducer. The light emitting device emits a beam along an optical axis. The light-transmissible ultrasonic transducer is disposed on the light emitting device at the optical axis and includes a transparent substrate and a plurality of ultrasonic transducer units. The plurality of ultrasonic transducer units is disposed on the transparent substrate and allows the beam to pass therethrough and be incident to the object to be tested along the optical axis, for coaxially receiving an ultrasound transmitted from the object to be tested along the optical axis after the beam is incident into the object to be tested.
