Simpler and faster microscopy system enabling broader biomedical applications

Optical-resolution photoacoustic microscopy (OR-PAM) has demonstrated great values in biomedical research. However, most OR-PAM systems suffer from limited imaging speed due to their inherent design limitation. A novel, two-dimensional multifocal OR-PAM system using a single-element ultrasonic transducer has been proposed. This system, termed as MFOR-PAMER, enables 400 times shorter scanning time than a conventional OR-PAM system at the same resolution and laser repetition rate. This system is envisaged with promising potential for many biomedical applications.
