Technological aspects of fiber optic image guides for needle endoscopes manufacturing

摘要

The results of technology research on high resolution fiber optic image guides (used in medical needle endoscopes) are presented. Work has been concentrated on optimization of image contrast and resolution of the image guide. Special attention has been paid to contrast enhancement and "cross-talk" phenomenon between pixels. The measurements of diffusion properties of different extra mural absorption (EMA) glasses have been carried out to find proper technology of the image guides manufacturing. As a result a comparison of transmission properties of different image guides is presented.
