The biological information imaging apparatus includes an acoustic wave detector 107 that detects an acoustic wave that is generated from a light absorber 105 and converts it to a first electrical signal; a photo-detector 110 that detects intensities of the light corresponding to a plurality of propagation distances of the light which propagates through the specimen 110 and converts it to a second electrical signal; a signal processing apparatus 111 that derives an average effective attenuation coefficient μeff of the specimen 110 based on the second electrical signal and derives an optical absorption coefficient μa of the specimen 110 based on the first electrical signal and the average effective attenuation coefficient μeff; and an image constructing apparatus 111 that constructs an image of the distribution of the optical absorption coefficient μa based on the distribution of the optical absorption coefficient μa. |
