Problems solved by technology
However, various factors can cause the coupling position to shift, which results in a loss of coupling efficiency, such as shock and vibration imparted to the optical port during shipping and setup, thermally induced expansion, rotation of the optomechanical mount used to guide the beam, and Deformation, thermally induced motion of the fiber port, or beam motion caused by movement of adjustable reflective elements within the system, such as rotatable or translatable variable beam splitters

An ophthalmic endo-illumination system (206) includes a light source that produces a light beam (305), a fiber port that receives an optical fiber (310), a condenser (302) that couples at least a portion of the light beam into the optical fiber received at the fiber port, and a beam splitter (304) disposed between the fiber port and the condenser. The beam splitter is configured to receive the light beam from the condenser and split the light beam into a first beam (312) which is coupled to the optical fiber and a second beam (314) which is coupled to a monitoring fiber (306). An optical sensor (308) is provided to detect an amount of the second beam output from the monitoring fiber. The coupling efficiency of the first beam coupled into the optical fiber may be determined based on the amount of the second beam output from the monitoring fiber.
Description
technical field [0001] The devices, systems and methods disclosed herein generally relate to the detection of the coupling efficiency of a light beam directed into an optical fiber. Background technique [0002] Intraocular illumination probes are used to provide illumination during ophthalmic surgery. In particular, intraocular illumination probes may be inserted into the eye to provide illumination inside the eye during ophthalmic surgery. Typically, an intraocular illumination probe is connected to an optical port of the intraocular illumination system to receive light from the intraocular illumination system. An intraocular illumination system may include a light source that produces light and a light collector that couples the light into an optical fiber of an intraocular illumination probe. [0003] During assembly of the optical port of the intraocular illumination system, the position and inclination of the beam from the concentrator are adjusted until the coupling...
