<p>The present invention provides a photoacoustic imaging apparatus, having: a light source (11); a plurality of detecting elements (31) for detecting an acoustic wave generated from (A) a surface (22) of an object (15) and (B) a light absorber (14) inside the object (15), and converting the acoustic wave into a detection signal; and a signal processor (20) for generating image data based on detection signals detected, wherein the signal processor (20) has: a Fourier transformer for performing Fourier transform, in a spatial direction, on the signals detected at a same receiving time so as to obtain spatial frequency signals; and an inverse - Fourier transformer for performing inverse Fourier- transform after reducing components exhibiting less than a predetermined frequency from among the spatial frequency signals so as to obtain second signals, the signal processor (20) generating image data using the second signals.</p> |
