A new discovery for a biomedical microscopy that can image into tissues to visualize absorbing structures is pioneered by a Systems Design Engineering professor. Dr. Parsin Haji Reza and his colleagues recently reported their work in Optica. By taking advantage of photoacoustic initial pressures, a functional all-optical non-contact optical-resolution photoacoustic microscopy is reported at depths beyond the optical transport mean-free-path of the excitation wavelength. The proposed method is capable of providing optical resolution images to depths of 2.5mm.
"There are many unsolved problems in robotics, and many opportunities for collaborations between like-minded researchers in Ontario and China," says Dr. John McPhee, Professor and Canada Research Chair in System Dynamics at the University of Waterloo, and one of the workshop presenters. [Read more]
