In the field of industrial endoscopy, optical imaging technology has been widely used for its excellent advantages of high resolution, high sensitivity and high speed. With the rapid development of industrial technology, the overhaul and maintenance of all kinds of equipment and machinery is becoming increasingly important. As an indispensable non-destructive testing equipment in modern industry, initially, industrial endoscopes are mainly used in aerospace systems, but with the in-depth understanding of its detection advantages, its application scope has gradually expanded to cover aviation, aerospace, civil aviation, petrochemical, electric power, ships, nuclear energy and other fields.

In the field of medical endoscopy, cross-scale optical imaging technology can realize the macroscopic and microscopic imaging of the observation site in a set of optical systems. In medical clinical practice, the cross-scale images of the sites observed by endoscopes can be obtained, which is conducive to the diagnosis of patients' conditions and the improvement of the accuracy of intraoperative operations. However, how to acquire, process and visualize endoscopic image information is the core problem to be solved by optical imaging technology. With the development of 3CMOS, intraoperative fluorescence imaging, spectrophotometry technology, 4K ultra HD resolution, 3D+4D imaging, AI-assisted, ultrasonic fusion and other related technologies mature innovation, the endoscope industry will usher in more accurate, high automation, high fidelity development opportunities.
