摘要： A light source apparatus includes light sources emitting first and second polarized light, an optical element transmitting one of the polarized light and reflecting the other, a polarization rotator generating polarization rotated light from the first polarized light, a wavelength convertor converting the second polarized light into wavelength converted light, and a controller. The optical element generates emitted light by combining the wavelength converted light and polarization rotated light. The controller acquires respective deterioration amounts of the light sources, and controls, based on respective changes in light emission amounts from the light sources acquired from the deterioration amounts, the light emission amount from at least one of the light sources for making different respective change amounts of the light emission amounts from the light sources, or changing a ratio between respective light emission amounts from the light sources.

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.
