Abstract
A photoacoustic imaging apparatus comprises: a light emitting unit emitting pulsed light with a wavelength absorbed inside a subject; a thin, flexible film applied to a skin surface of the subject to make the pulsed light transmit it and reflects the light on its outer surface at the same time; a multi-directional light emitting unit emitting a plurality of visible light beams from multi-directions to the outer surface of the thin film; a micro-vibration detection unit detects, on the basis of diffraction and/or interference of a plurality of reflected light obtained from the outer surface of the thin film, a state of causing micro-vibrations of the thin film as the photoacoustic waves generated from the light absorber collide against an inner backside of the thin film; and a shape image transformation unit that produces the images of a shape of the light absorber as detected by the micro-vibration detection unit.
