OBJECT INFORMATION ACQUIRING APPARATUS AND CONTROL METHOD THEREOF
First Claim
1. An object information acquiring apparatus comprising:
- an irradiating unit configured to irradiate an object with light;
an irradiation position controlling unit configured to control an irradiation position for irradiating the object with the light;
a probe configured to receive an acoustic wave generated when the object is irradiated with the light from the irradiating unit, at a position substantially opposing the irradiating unit across the object, and output an acoustic wave signal;
a probe controlling unit configured to control reception of the probe;
a control processor configured to control at least one of the irradiation position controlling unit and the probe controlling unit such that the light does not enter the probe directly without going through the object; and
a constructing unit configured to construct characteristic information on an inside of the object from the acoustic wave signal.

Abstract
There is used an object information acquiring apparatus including an irradiating unit that irradiates an object with light, an irradiation position controlling unit that controls an irradiation position for irradiating the object with the light, a probe that receives an acoustic wave generated when the object is irradiated with the light from the irradiating unit, at a position opposing the irradiating unit across the object, and outputs an acoustic wave signal, a probe controlling unit that controls the probe, a control processor that controls at least one of the irradiation position controlling unit and the probe controlling unit such that the light does not enter the probe directly without going through the object, and a constructing unit that constructs characteristic information.

16. A control method of an object information acquiring apparatus having an irradiating unit, an irradiation position controlling unit, a probe, a probe controlling unit, a control processor, and a constructing unit, the control method comprising:
-
an irradiating step in which the irradiating unit irradiates an object with light; an irradiation position controlling step in which the irradiation position controlling unit controls an irradiation position for irradiating the object with the light; a receiving step in which the probe receives an acoustic wave generated when the object is irradiated with the light from the irradiating unit, at a position opposing the irradiating unit across the object, and outputs an acoustic wave signal; a probe controlling step in which the probe controlling unit controls the probe when the probe receives the acoustic wave; a controlling step in which the control processor controls at least one of the irradiation position controlling unit and the probe controlling unit such that the light does not enter the probe directly without going through the object; and a constructing step in which the constructing unit constructs characteristic information on an inside of the object from the acoustic wave signal.
