APPARATUS

摘要

An apparatus includes a plurality of acoustic detectors detecting an acoustic wave from an object and outputting an electric signal, including a first and a second acoustic detectors each having a first and a second frequency sensitivity characteristics to output a first and a second electric signals, the first and the second frequency sensitivity characteristics are different, a memory holding a correction function created based on a third frequency sensitivity characteristics obtained from the first and the second frequency sensitivity characteristics, and an information processor correcting the first and the second electric signals using the correction function, thereby acquiring corrected electric signals and generating image data representing object information.

主权项

1. An apparatus comprising:
a light source; a plurality of acoustic detectors configured to detect an acoustic wave generated from an object irradiated with light from the light source and output an electric signal, the plurality of acoustic detectors including a first acoustic detector having a first frequency sensitivity characteristics to output a first electric signal and a second acoustic detector having a second frequency sensitivity characteristics, which is different from the first frequency sensitivity characteristics, to output a second electric signal; a memory configured to hold a correction function created based on a third frequency sensitivity characteristics obtained based on the first and the second frequency sensitivity characteristics; and an information processor configured to: (a) read the correction function from the memory, (b) correct the first and second electric signals in accordance with the correction function, thereby acquiring corrected first and second electric signals, and, (c) generate image data representing object information using the corrected first and second electric signals.
