Abstract
A confocal photoacoustic microscopy system includes a laser configured to emit a light pulse, a focusing assembly configured to receive the light pulse and to focus the light pulse into an area inside an object, an ultrasonic transducer configured to receive acoustic waves emitted by the object in response to the light pulse, and an electronic system configured to process the acoustic waves and to generate an image of the area inside the object. The focusing assembly is further configured to focus the light pulse on the object in such a way that a focal point of the focusing assembly coincides with a focal point of the at least one ultrasonic transducer.
