    Abstract: An object information acquiring apparatus comprises a light irradiation unit configured to irradiate lights having different wavelengths respectively; an acoustic wave receiving unit configured to receive an acoustic wave by each of the lights having different wavelengths respectively, and convert into an electric signal that corresponds to each of the lights having different wavelengths; a characteristic information acquiring unit configured to acquire characteristic distribution related to each position in the object based on the electric signal; a statistics acquiring unit configured to acquire a histogram from the characteristic distribution; and an image information acquiring unit configured to acquire image information causing a display device to display the characteristic distribution in the object and the histogram.

    Abstract: Improved thermoacoustic imaging is provided by ensuring directional uniformity of the microwave excitation provided to the target being imaged. This directional uniformity can be quantified in terms of the eccentricity e of the polarization ellipse of the microwave excitation. We have e≦0.87, preferably e≦0.71, and more preferably e≦0.32. Optical excitation can be provided in addition to the microwave excitation. Excitation can be performed at multiple optical wavelengths and/or microwave frequencies to improve depth uniformity. In addition, the employment of excitation cells with optimized spacing and geometry provides the uniformity in another two degrees of freedom. One potential application is to detect blood vessel in user's finger for biometric authentication.
