1. A probe for photoacoustic tomography comprising:
a first Powell lens and a second Powell lens, which are spaced a predetermined distance apart from each other, for converting a first beam and a second beam having a circular cross section into a first line beam and a second line beam with uniform energy distribution, respectively;
a cylindrical lens disposed in a traveling direction of the first line beam and the second line beam so that the first line beam and the second line beam have a constant width and a constant thickness while the first line beam and the second line beam pass therethrough the cylindrical lens, wherein the first line beam and the second line beam are in parallel with each other;
a pair of light path changing members for changing light paths of the first line beam and the second line beam from the cylindrical lens, respectively, thereby focusing on a target area; and
an acoustic measurement unit for receiving an acoustic wave outputted from the target area in response to the first line beam and the second line beam focused on the target area.
