Abstract
An object information acquiring apparatus includes a probe configured to detect a photoacoustic wave generated from an object irradiated with light, a signal collector configured to generate a first detection signal from the photoacoustic wave, a signal processor configured to generate, from the first detection signal, a second detection signal in which a component having a phase inverted from the phase of a component deriving from the photoacoustic wave is reduced, by using a differential signal of an impulse response of the probe, and an image generator configured to generate image data on the inside of the object using the second detection signal.

An object information acquiring apparatus comprising:
- a probe configured to detect a photoacoustic wave generated from an object irradiated with light;
- a signal collector configured to generate a first detection signal from the photoacoustic wave;
- a signal processor configured to generate, from the first detection signal, a second detection signal in which a component having a phase inverted from the phase of a component deriving from the photoacoustic wave is reduced, by using a differential signal of an impulse response of the probe;
- and
- an image generator configured to generate image data on the inside of the object using the second detection signal.
A control method for an object information acquiring apparatus including a probe configured to detect a photoacoustic wave generated from an object irradiated with light, a signal collector, a signal processor, and an image generator, the control method comprising:
- the signal collector generating a first detection signal from the photoacoustic wave;
- the signal processor generating, from the first detection signal, a second detection signal in which a component having a phase inverted from the phase of a component deriving from the photoacoustic wave is reduced, by using a differential signal of an impulse response of the probe;
- and
- the image generator generating image data on the inside of the object using the second detection signal.
