Abstract: Provided is an optical measurement apparatus including: a polarized light irradiation unit 10 that irradiates a subject Ob with irradiation light of which polarization is controlled; and a polarization imaging unit 20 that images a polarization state of measurement light occurring due to scattering, reflection, absorption, or the like of the irradiation light by the subject Ob, calculates all or a part of Stokes parameters of the measurement light, and measures a variation of a polarized component occurring between the irradiation light and the measurement light due to the subject Ob. Since the subject is irradiated with irradiation light of which a polarization state is controlled, it is possible to acquire subject information that is difficult to measure in a case of irradiating the subject with natural light, that is, non-polarized irradiation light, and it is also possible to suppress noise or a decrease in contrast that occurs when measuring polarization by irradiating the subject with irradiation light of which a polarization state is unstable.

Abstract: An ultrasonic inspection device includes: a longitudinal ultrasonic sensor configured to emit and receive a longitudinal ultrasonic wave; and an ultrasonic transducer unit made of metal and having the shape of a polyhedron. The ultrasonic transducer unit includes: an output surface configured to be disposed facing an object to be inspected; an input surface on which the longitudinal ultrasonic sensor is disposed; and a conversion surface configured to, when the longitudinal ultrasonic wave input through the input surface is reflected by the conversion surface, convert the longitudinal ultrasonic wave into a transverse ultrasonic wave such that the transverse ultrasonic wave propagates toward the output surface, the conversion surface being tilted at a predetermined angle with respect to an in-plane direction of the output surface. Thermal conductivity of the ultrasonic transducer unit is lower than thermal conductivity of the object to be inspected.
