title = "Photoacoustic imaging by using a bundle of thin hollow-optical fibers",
abstract = "We propose a photoacoustic imaging system composed of a flexible bundle of thin hollow-optical fibers that enables endoscopic diagnosis. The hollow-fiber bundle involves 37 fibers with an inner diameter of 100 μm and the total diameter of the bundle is 1.2 mm. A laser beam for photoacoustic excitation is scanned at the input end of fiber bundle and therefore, no scanning mechanism is necessary at the distal end. In addition, owing to the small numerical aperture of hollow optical fibers, a high resolution image is obtained without using a micro-lens array at the end. By using the fiber bundle probe, photoacoustic imaging of blood vessels in the ovarian membrane of fish were successfully obtained with a laser fluence of around 2.8 mJ/cm2.",
