Title:
OPTICAL IMAGING PROBE
Document Type and Number:
WIPO Patent Application WO/2015/102081
Kind Code:
A1
Abstract:
Provided is a 3D-scanning optical imaging probe which inhibits rotation unevenness of rotational sections, shaft run-out, friction, and rotation transmission delay by reducing the occurrence of torque loss and rotation transmission delay, and which is capable of obtaining 3D scans and observation images within a fixed frontal range. A substantially tubular catheter has, provided along substantially the same line therein: a fixed-side optical fibre; a first optical path conversion means which is rotationally driven by a first motor, and which rotates and emits a beam of light forwards and tilted at an angle with respect to a rotational axis; and a second optical path conversion means which, at a tip side of a rotation-side optical fibre rotationally driven by a second motor, tilts an optical path by a micro-angle with respect to the rotational axis, and rotates and emits the beam of light to irradiate the first optical path conversion means therewith. By controlling the two rotational frequencies of the first optical path conversion means and the second optical path conversion means, the emission angle of the beam of light is changed and the beam of light is emitted towards a frontal 3D area. As a result, high-quality 3D observation images can be obtained.
