Abstract: A fundus imaging apparatus includes an illumination apparatus including a light source and an illumination optical system, and an imaging apparatus including an image sensor and an imaging optical system. The illumination optical system irradiates a fundus with light from the light source. The imaging optical system forms an image of the fundus on the image sensor. An optical axis of the illumination optical system does not match an optical axis of the imaging optical system, or the illumination optical system does not have a specific optical axis.

Abstract: A photoacoustic element which has excellent optical properties and acoustic properties is achieved. The photoacoustc element (1) includes: a metal layer (10); a first member (11) which is bonded to one primary surface of the metal layer (10); and a second member (12) which is bonded to another primary surface of the metal layer (10). The metal layer (10) reflects optical waves and transmits pohotoacoustic waves stemming from optical waves. Materials of the metal layer (10), the first member (11), and the second member (12) are selected so as to match an acoustic impedance of the metal layer (10) and an acoustic impedance of each of the first member (11) and the second member (12).
