Abstract
A photoacoustic imager includes a light source portion, a detection portion, and an imaging portion, and the imaging portion is configured to generate a photoacoustic wave image indicating a detection object in motion by acquiring difference data of signals acquired on the basis of a plurality of photoacoustic wave signals detected at different times of generated photoacoustic wave signals.

A photoacoustic imager comprising:
- a light source portion that applies light to a specimen;
- a detection portion that detects an acoustic wave generated by absorption of the light applied from the light source portion to the specimen by a detection object in the specimen and generates photoacoustic wave signals;
- and
- an imaging portion that generates a photoacoustic wave image indicating the detection object in motion by acquiring difference data of signals acquired on the basis of a plurality of the photoacoustic wave signals detected at different times of the photoacoustic wave signals to extract portions in which intensities of the photoacoustic wave signals temporally change.
