Abstract

See full text

An object information acquiring apparatus includes: a light source that generates a first light beam; a receiving unit that includes an irradiating unit emitting the first light beam so as to be directed to a predetermined optical focusing region and an acoustic wave detecting unit detecting a first acoustic wave generated when the first light beam is emitted to an object; a scanning unit that performs relative movement between the object and the receiving unit so that the receiving unit follows a concave or convex shape of a surface of the object while the first light beam is emitted and the first acoustic wave is detected; and an acquiring unit that acquires characteristics information on the optical focusing region of the object based on a detection result obtained by the acoustic wave detecting unit.
