用于血管成形术面开发的一种金属端纤维或称“激光探针”,其光学纤维的端部为一金属探头,该探头由氩离子或Nd:YAG激光器加热并加于将被汽化的组织上。被另加热的探头产生与探头温度成比例的红外辐射。本文研究了利用检测经纤维传输返回的红外线以测量探头温度的反馈控制系统的可行性。这个探头先与热表面物理接触而加热,然后用氩离子激光器经光学纤维对其加热。返射回的红外射线被硫化铅检测器感知,而且探头的温度同
A metal-edge fiber or “laser probe” for the development of angioplasty surfaces with the end of the optical fiber being a metal probe heated by an argon ion or Nd: YAG laser and applied to the metal to be vaporized Organized. The probe heated by another probe generates infrared radiation proportional to probe temperature. This paper investigates the feasibility of using a feedback control system that measures the temperature of the probe by detecting the infrared returned by the fiber transmission. The probe is first heated in physical contact with the hot surface and then heated by optical fibers using an argon ion laser. The returned infrared radiation is detected by the lead sulfide detector and the temperature of the probe is the same
