Abstract
Provided is an apparatus for acquiring object information, the apparatus including: first and second laser output unit outputting first and second pulsed laser; a laser controlling unit configured to control each laser output unit; a first or second detecting unit configured to detect an emission timing of laser and output a first or second detection signal; a probe configured to receive an acoustic wave from an object being irradiated with the laser; and a signal processing unit configured to acquire specific information of the object, based on the acoustic wave. The laser controlling unit controls output of at least one of the laser output units so as to decrease a time difference between subsequent first and second pulsed lasers to be output.
