Abstract
The present invention relates to a portable probe for photoacoustic tomography, capable of performing line-by-line scanning or area-by-area scanning by using a small number of light inputs; and a real-time photoacoustic tomography device. The probe for photoacoustic tomography includes: a lens receiving light inputs from an optical fiber so as to make the same proceed as small diameter parallel light; a Powell lens receiving the small diameter parallel light and generating a line beam of a predetermined thickness, and allowing energy dispersed on a line to be uniform on the entire line; a lens making the line beam pass therethrough such that the line beam has a predetermined width and a reduced thickness so as to be line-focused at a target area; an acoustic reflection glass for separating, from a light path, an acoustic wave outputted from the target area; and an acoustic measurement unit for measuring acoustic strength.
