摘要： A DBR semiconductor laser is controlled in an image projecting apparatus, which includes the DBR laser having a phase and DBR region, a light wavelength converting device for converting fundamental-wave light emitted from the DBR laser into second harmonic wave light, an optical deflector for scanning the second harmonic wave in a one or two-dimensional manner, and a modulating portion for modulating the DBR laser. Coefficient calculating and wavelength adjusting steps are performed within a non-drawing time. The coefficient calculating step calculates at least one coefficient in a relationship between a DBR current to be injected into the DBR region and a phase current to be injected into the phase region for continuously shifting the wavelength of the fundamental-wave light. The wavelength adjusting step changes DBR current injected into the DBR region and phase current injected into the phase region based on the relationship.

摘要： This invention employs an object information acquiring apparatus including a probe for receiving, as a received signal, an acoustic wave which is generated within an object irradiated with light and propagates on an object surface, and a processor for generating object information, which is information based on an internal optical characteristic value of the object, by using intensity of the received signal. The processor corrects the intensity of the received signal by using the reflectance upon the acoustic wave entering the probe which is calculated based on the angle of the acoustic wave entering the probe, and on the acoustic impedance and acoustic velocity of the object and the probe.

摘要： In photoacoustic imaging, in cases where an emitted light amount and a beam pattern of a laser vary according to variation with time and external factors, and cases where the wavelength and the repetition rate of the laser vary, there is a danger that a light fluence of light applied to tissue become too strong. A unit is provided for measuring a distribution of light fluence of light applied to the tissue. A measuring apparatus is provided that controls output of a laser source such that the measured light fluence should not exceed the maximum permissible exposure to the tissue. Accordingly, highly safe photoacoustic imaging to the tissue can be realized.
