Description
本發明係一種光纖檢測技術領域，尤指一種自受測組件所延伸出的光纖引導進行水平量測的光纖輔助夾具、光纖量測治具以及光纖檢測儀。 The present invention relates to the technical field of optical fiber detection, in particular to an optical fiber auxiliary fixture, optical fiber measuring jig and optical fiber detector for horizontal measurement guided by the optical fiber extended from the tested component.
光纖是光導纖維的簡寫，是一種由玻璃或塑膠製成的纖維，可作為光傳導工具。微細的光纖通過封裝在塑膠護套中，使得它能夠彎曲而不至於斷裂。通常，光纖的一端的發射裝置使用發光二極體(light emitting diode，LED)或一束鐳射將光脈衝傳送至光纖，光纖的另一端的接收裝置使用光敏元件檢測脈衝。光纖標準多、參數複雜、一般的非專業人員很難理解，主要可分為多模光纖以及單模光纖。多模光纖(Multi Mode Fiber)：中心玻璃芯較粗(50或62.5μm)，可傳多種模式的光。但其模間色散較大，這限制了傳輸數位信號的頻率，而且隨距離的增加會更加嚴重。單模光纖(Single Mode Fiber)：中心玻璃芯很細(芯徑一般為9或10μm)，只能傳一種模式的光。因此其模間色散很小，適用於遠端通訊，但還存在著材料色散和波導色散，這樣單模光纖對光源的譜寬和穩定性有較高的要求，即譜寬要窄，穩定性要好。 Optical fiber is short for optical fiber. It is a fiber made of glass or plastic and can be used as a light transmission tool. The tiny optical fiber is encapsulated in a plastic sheath, so that it can be bent without breaking. Generally, the transmitting device at one end of the optical fiber uses a light emitting diode (LED) or a beam of laser to transmit light pulses to the optical fiber, and the receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulses. There are many optical fiber standards, complex parameters, and it is difficult for ordinary non-professionals to understand them. They can be divided into multi-mode optical fibers and single-mode optical fibers. Multi Mode Fiber: The central glass core is thicker (50 or 62.5μm), which can transmit multiple modes of light. However, the inter-mode dispersion is large, which limits the frequency of transmitting digital signals, and it becomes more serious with the increase of distance. Single Mode Fiber (Single Mode Fiber): The central glass core is very thin (the core diameter is generally 9 or 10 μm) and can only transmit light in one mode. Therefore, the inter-mode dispersion is very small, which is suitable for remote communication, but there are material dispersion and waveguide dispersion. In this way, single-mode fibers have higher requirements on the spectral width and stability of the light source, that is, the spectral width should be narrow and stable. Better.
目前量測設備都是以光纖輸入最為普遍，然而相關耦光的透鏡及固裝結構太大，無法同時搭配顯微鏡來微調耦光機制，現行的光纖量測治具會被治具結構的限制檔住而不易操作；此外，因為透鏡光纖的聚焦及收光的能力非常好，外觀尺寸也只有125μm到240μm(常用尺寸)，因此需要有搭配移動平台的延伸且容易在顯微鏡底下做細微的調整的功能，然而因為現行的光纖量測治具的結構限制，使得前述需求難以實現；再者，在進行量測時，治具結構中的輔助夾具的設計也相當重要。因為，輔助夾具除了導引光纖的行進方向之外，也要能在進行任一種光纖量測時，都有最小彎曲直徑以至於不會產生損耗的功能，因此如何能夠讓光纖具有特定角度範圍以入射到待測元件上，以解決上述結構限制以及光損的問題，是有待解決的重要課題。 At present, optical fiber input is the most common measurement equipment. However, the relevant coupling lens and fixed structure are too large to be used with a microscope to fine-tune the coupling mechanism. The current optical fiber measurement fixture will be restricted by the fixture structure. It is not easy to operate; in addition, because the lens fiber has very good focusing and light collection capabilities, the appearance size is only 125μm to 240μm (common size), so it needs to be extended with a mobile platform and easy to make fine adjustments under the microscope However, due to the structural limitations of the current optical fiber measuring fixture, the aforementioned requirements are difficult to achieve; in addition, the design of the auxiliary fixture in the fixture structure is also very important when measuring. Because the auxiliary fixture not only guides the direction of fiber travel, but also has the function of having the smallest bend diameter so that no loss occurs when performing any type of fiber measurement. Therefore, how can the fiber have a specific angle range? Incident to the device under test to solve the above-mentioned structural limitation and light loss problems is an important issue to be solved.

補充說明，該裸光纖部LB3的尖端距離光纖試片S的間距主要根據量測平台上方的顯微成像單元13觀測能力做設定；為了讓耦光的功率及光斑可以均勻，基本上大於80度的入射角度將是比較合適的耦光角度，因此延伸的光纖與角度的搭配也要計算避免阻擋到上方顯微成像單元13的影像判斷。通過以雷射收光方式引導光線進入到光纖中，就能導引進入光纖檢測儀進行測試，藉由透鏡光纖進行聚焦的能力，將光能量耦入極小的Photodiode chip中，就可以轉換電流達到訊號處理的分析。

綜上所述，本發明所述之光纖輔助夾具、光纖量測治具以及光纖檢測儀，通過光纖輔助夾具的元件組成以及配置，藉由可活動夾持的方式以使光纖壓合固定並形成弧向彎曲延伸，讓光纖能夠大於80度角的入射到待測元件上，使用斜角及彎曲壓片的結構設計來達到這個沒有光損的彎曲功能，再者上方的顯微鏡也不會受到導槽的遮擋影響耦光的判斷，從而使光纖的受測部分與量測試片形成水平配置並進行量測作業。光纖輔助夾具所搭配的透鏡光纖會依照客戶需求來製作，選用的波長，光纖的導光直徑，焦距都直接會影響到耦光的效率，量測平移台則是微動的設計讓透鏡光纖以微米的解析度調整以取得最佳的耦光效率。 In summary, the optical fiber auxiliary fixture, optical fiber measuring fixture, and optical fiber detector of the present invention are composed and configured by the components of the optical fiber auxiliary fixture, and the optical fiber is pressed and fixed and formed by a movable clamping method. The arc is bent and extended, so that the optical fiber can be incident on the component under test at an angle greater than 80 degrees. The structure design of the oblique angle and the bending sheet is used to achieve this bending function without light loss, and the upper microscope will not be guided. The occlusion of the groove affects the judgment of light coupling, so that the tested part of the optical fiber and the measurement test piece form a horizontal configuration and perform measurement operations. The lens fiber used in the fiber auxiliary fixture will be made according to customer needs. The selected wavelength, the diameter of the fiber's light guide, and the focal length will directly affect the efficiency of the light coupling. The measurement translation stage is micro-moving design so that the lens fiber is in micrometers. The resolution is adjusted to obtain the best coupling efficiency.
