Abstract: A probe includes an optical system which irradiates a site of a biological tissue and receives light emitted from the site, and an imaging device. The imaging device is disposed ahead of the optical system closer to the end of the probe. The probe rotates the incident direction of the light and the imaging direction of the imaging device around a rotation axis directed to the longitudinal direction of the probe while fixing an angle between the incident direction and the imaging direction. The optical system receives the light from the site which always falls in the field of view of the imaging device, or brought with a time lag into the field of view of the imaging device as a result of rotation, the light being incident in the direction normal to, or inclined away from the rotation axis.

In the optical connector, optical fibers are inserted into a lumen of a tube from opposite ends thereof; one of the optical fibers is fixed to the tube and the other optical fiber is held so as to be rotatable relative to the tube; an end of one of the optical fibers is separated from an end of the other optical fiber to form a gap therebetween in the lumen; a connecting section which connects the exterior space of the tube and the gap is formed; and a liquid or fluid made of a material which can transmit light is held in the exterior space, the gap, and the connecting section. Consequently, a significant pressure variation in matching liquid does not occur if the distance between the facing optical fibers changes.
