<P>PROBLEM TO BE SOLVED: To solve the problem: an increase in light emission frequency to shorten an obtaining time of a reception signal causes a decrease in SNR (signal-to-noise ratio) because an exposure amount must be lowered. <P>SOLUTION: This subject information obtaining apparatus includes: a probe having a receiver for receiving an acoustic wave to be converted to an electric signal, and first and second irradiation units for irradiating mutually different areas on a subject surface with pulsed light; and a control unit for controlling illumination positions of the pulsed light to avoid continuous irradiation of the subject with the pulsed light from the first and second irradiation units. <P>COPYRIGHT: (C)2013,JPO&INPIT |
