Conventional imaging and detection methods face challenges in accessing small areas in industries like medicine and industry. Endoscopes offer detailed multi-dimensional image data in a compact, flexible form, facilitating enhanced diagnosis, identification, and monitoring. Fiber bundles, as the key components of flexible miniature endoscopes, consist of numerous spatial channels with fiber cores just a few hundred microns in diameter, facilitating direct transmission of two-dimensional images. However, image quality and resolution are often constrained by the size and spacing of the fiber core, posing challenges to meet increasing demands.
