View Patent ↗Provided is an optical probe. The optical probe includes an optical input/output unit, a rotation part spaced apart from the optical input/output unit in a first direction and including a reflection surface, and a transparent electrode provided around the reflection surface.
1. An optical probe comprising:
an optical input/output unit;
a rotation part spaced apart from the optical input/output unit in a first direction and including a reflection surface; and
a transparent electrode surrounding the reflection surface.
2. The optical probe of claim 1 , wherein the reflection surface has an acute angle or obtuse angle with the first direction.
3. The optical probe of claim 1 , wherein the optical input/output unit comprises a lens and an optical fiber extending in the first direction.
4. The optical probe of claim 3 , further comprising an optical fiber bundle surrounding the optical fiber and the lens.
5. The optical probe of claim 1 , further comprising a housing surrounding the optical input/output unit, the rotation part, and the transparent electrode.
6. The optical probe of claim 5 , further comprising:
a first power path located in the housing and extending in the first direction along the optical input/output unit; and
a second power path located in the housing and extending in the first direction along the rotation part.
7. The optical probe of claim 6 , wherein the transparent electrode is electrically connected to the first power path and the second power path.
8. The optical probe of claim 7 , wherein the transparent electrode further extends in the first direction along the optical input/output unit and the rotation part.
9. The optical probe of claim 5 , wherein the housing comprises a transparent material.
10. The optical probe of claim 1 , wherein the transparent electrode comprises an anode transparent electrode and a cathode transparent electrode,
wherein the anode transparent electrode and the cathode transparent electrode are spaced apart from each other in a second direction intersecting the first direction.
11. The optical probe of claim 1 , wherein a length of the transparent electrode extending along the first direction is shorter than the optical input/output unit and the rotation part extending along the first direction.
12. The optical probe of claim 1 , further comprising:
an optical window part located in the first direction relative to the optical input/output unit;
wherein the reflection surface is configured to reflect light transmitted from the optical input/output unit through the optical window part onto a detection target.
13. The optical probe of claim 1 , wherein the rotation part is rotated using the first direction as an axis.
14. An optical probe system comprising:
an optical probe; and
a light source unit configured to supply light to the optical probe,
wherein the optical probe comprises:
an optical input/output unit;
a rotation part spaced apart from the optical input/output unit in a first direction and including a reflection surface; and
a transparent electrode surrounding the reflection surface.
15. The optical probe system of claim 14 , further comprising a control unit for controlling the light source unit and the optical probe.
16. The optical probe system of claim 14 , wherein the optical input/output unit comprises a lens and an optical fiber extending in the first direction.
