Abstract
We have analyzed the output characteristics of the photoacoustic signal according to the laser wavelength. Also, we have investigated the output characteristics of the photoacoustic signal for aortic tissue and hemoglobin. Especially, we have considered the influence of a disturbance at the boundary of the object on the output of the photoacoustic signal when the laser irradiates the object. With these results, we investigated the output characteristics of photoacoustic signals at 1340~nm and 1525~nm for aortic tissue and at 355~nm and 532~nm for hemoglobin. As a result, the strongest photoacoustic signal was found to be generated at 1525~nm for aortic tissue and at 355~nm for hemoglobin.
