工業內窺鏡檢測與其他無損檢測方式大的不同是，它可以直接反映出被檢測物體內外表面的情況，而不需要通過數據的對比或檢測人員的技能和經驗來判斷缺陷的存在與否。并且在檢測的同時，我們可以使用工業內窺鏡設備對整個檢測過程進行動態的錄影記錄或照相記錄，并能對發現的缺陷進行定量分析，測量缺陷的長度，面積等數據。
The big difference between industrial endoscopic testing and other nondestructive testing methods is that it can directly reflect the internal and external surfaces of the tested object, without judging the existence of defects through data comparison or the skills and experience of testers. At the same time of detection, we can use industrial endoscope equipment to dynamically record or photograph the whole detection process, quantitatively analyze the defects found, and measure the length, area and other data of defects.
軟性內窺鏡領域壁壘極高，由于日本企業在光學領域的技術積累和領先水平，全球范圍的市場基本被奧林巴斯、賓得、富士等日企瓜分，合計占據90%以上的市場份額。
The barriers in the field of soft endoscopes are extremely high. Due to the technical accumulation and leading level of Japanese enterprises in the optical field, the global market is basically divided by Japanese enterprises such as Olympus, Pentax and Fuji, accounting for more than 90% of the market share.
產品與產品在光學積累和加工工藝上存在較大差距，進口替代進程緩慢。部分國產企業(上海成運、上海醫光、上海澳華光電)有涉及消化道軟鏡，但是以較為低端的標清產品為主，開立和澳華近年推出了國產高清消化道軟鏡，性能有一定提升，但是目前客戶主要以二級及以下醫院采購為主，進入三級醫院存在難度。

There is a big gap between products in optical accumulation and processing technology, and the process of import substitution is slow. Some domestic enterprises (Shanghai Chengyun, Shanghai Yiguang and Shanghai Aohua Optoelectronics) are involved in digestive tract soft mirrors, but they mainly focus on low-end standard definition products. Kaikai and Aohua have launched domestic high-definition digestive tract soft mirrors in recent years, and their performance has been improved to a certain extent. However, at present, customers mainly purchase from level II and below hospitals, so it is difficult to enter level III hospitals.
①內窺鏡行業技術壁壘極高：內窺鏡是集光學、電子、結構、材料等多學科技術為一體的器械，技術壁壘極高。鏡體內部包含多個通道，包括照明光纖、傳像光纖、傳氣通道、傳水通道等，需要多個專業領域的人才相互配合。
① The endoscope industry has extremely high technical barriers: the endoscope is an instrument integrating multi-disciplinary technologies such as optics, electronics, structure and materials, with extremely high technical barriers. The interior of the mirror body contains multiple channels, including lighting fiber, image fiber, air channel, water channel, etc., which need the cooperation of talents in multiple professional fields.
光學技術：核心部件是鏡頭和圖像傳感器，技術難點是攝像頭光學模組設計。
Optical technology: the core components are lens and image sensor, and the technical difficulty is the design of camera optical module.
圖像處理算法與成像：降噪技術和邊緣增強技術，例如NBI窄帶成像技術和FICE分光技術等，且日本廠家已經申請了很多專利進行保護。
Image processing algorithm and imaging: noise reduction technology and edge enhancement technology, such as NBI narrowband imaging technology and fice spectroscopy technology, and Japanese manufacturers have applied for many patents for protection.
材料與加工工藝：在細微構造、材料等方面，有大量的專利和技術要訣。例如找到軟硬適中的材料適于插入，量產超細部分加工與組裝工藝。
Materials and processing technology: there are a large number of patents and technical know-how in terms of fine structure and materials. For example, find materials with moderate hardness and softness suitable for insertion and mass production of ultra-fine part processing and assembly process.
②先發優勢明顯，老牌企業已建立產業護城河。
② The first mover advantage is obvious, and the old enterprises have established an industrial moat.
