Embodiment Construction

[0070] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the following combination Figure 1 to Figure 5 And embodiment, the present invention is described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0071] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.

[0072] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right",...

Abstract

The embodiment of the invention discloses an optical component position control device and an optical fiber measurement system. The device includes an optical assembly, a moving frame assembly, a displacement driving mechanism, an X-direction fine-tuning mechanism and a Z-direction fine-tuning mechanism; the optical assembly includes at least one optical component; the displacement driving mechanism is used to drive the moving frame At least a part of the assembly, so that the optical component can quickly move into or out of the measurement optical path in the X direction; the X direction fine-tuning mechanism is used to adjust the optical component in the X direction The position is fine-tuned; the Z-direction fine-tuning mechanism is used for fine-tuning the position of the optical component in the Z-direction. The system includes the device. Embodiments of the present invention enable fast and precise positioning of optical components such as diaphragms.

Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to an optical component position control device and an optical fiber measurement system. Background technique [0002] Optical fiber communication has gradually become the most important wired communication method because of its advantages of large transmission capacity and good confidentiality. The foundation supporting the development of this technology is the rapid development of fiber optic cable manufacturing technology. [0003] Long-distance optical fiber communication cables are mainly made of single-mode optical fiber bundles. One of the main characteristic parameters characterizing the transmission performance of single-mode fiber is the mode field diameter (MFD, Mode Field Diameter), which reflects the distribution state of the fundamental mode light in the core area of ​​the single-mode fiber, and directly affects the joint loss and bending resistance of the...
