OPTICAL IMAGING PROBE |
摘要 |
Provided is an optical imaging probe that is able to obtain a stable observation image by a dynamic pressure bearing.;An optical imaging probe for guiding rearward a light entering a front end includes: a rotation driving source (10) adapted to drive and rotate a rotor (11); a tubular rotation shaft (20) inserted and fixed over an axial direction in a rotation center side of the rotor (11); an optical fiber (30) inserted in the tubular rotation shaft (20), the front end of which a light is able to enter; and a bearing member (41, 42) supporting the tubular rotation shaft (20) in a rotatable manner, and the bearing member (41, 42) configures a dynamic pressure bearing adapted to generate a high lubricating oil film pressure locally at multiple positions in a circumference direction. |

1. An optical imaging probe for guiding rearward a light entering a front end, comprising:
a rotation driving source adapted to drive and rotate a rotor; a tubular rotation shaft inserted and fixed over an axial direction in a rotation center side of the rotor; an optical fiber inserted in the tubular rotation shaft, a front end of which a light is able to enter; and a bearing member supporting the tubular rotation shaft in a rotatable manner, wherein the bearing member includes a dynamic pressure bearing adapted to generate a high lubricating oil film pressure locally at multiple positions in a circumference direction. |
