<p>A probe (50) irradiates light upon an object to be measured and receives return light from the object to be measured. The probe (50) includes: an optical path (21) for transmitting the light from a light source (10); a mirror member (52) for reflecting the light transmitted by the optical path (21); and a rotational oscillation mechanism (56) for causing the rotational oscillation of the end portion of the optical path (21) and the mirror member (52) around the longitudinal axis of the optical path (21). The rotational oscillation mechanism (56) induces rotational oscillation within the limits of the torsional elasticity of the optical path (21). As a result of this configuration, it is possible to suppress light loss and ghosting due to reflections and obtain a highly-reliable rotary optical probe with a simple configuration.</p> |
