Eyewear-style three-dimensional endoscope derived from microstructured polymer fiber with the function of image transmission

摘要

A method of fabricating multi-core polymer image fiber is proposed.Image fiber preform is fabricated by stacking thousands of polymer fibers each with a 0.25-mm diameter orderly in a die by only one step.The preform is heated and stretched into image fiber with an outer diameter of 2 mm.Then a portable eyewear-style three-dimensional (3D) endoscope system is designed,fabricated,and characterized.This endoscopic system is composed of two graded index lenses,two pieces of 0.35-m length image guide fibers,and a pair of oculars.It shows good flexibility and portability,and can provide the depth information accordingly.
