Coupling of rigid to flexible imaging multifibers

Area of Science:

• Optical Engineering
• Medical Imaging
• Materials Science

Background:

• Traditional endoscopy faces limitations in balancing image resolution with flexibility.
• Miniature rigid endoscopes offer high resolution but lack maneuverability.
• Existing flexible endoscopic systems often compromise image quality.

Purpose of the Study:

• To develop a novel endoscopic instrument integrating high resolution and flexibility.
• To theoretically and experimentally validate the performance of coupled multifiber systems.
• To enhance imaging capabilities for percutaneous endoscopy and industrial applications.

Main Methods:

• Magnifying images from a rigid miniature endoscope onto a large flexible multifiber.
• Theoretical analysis of the Modulation Transfer Function (MTF) for coupled multifiber systems.
• Experimental verification of the MTF and performance comparison with existing systems.

Main Results:

• The developed instrument successfully combines high resolution and flexibility.
• The MTF of coupled multifibers was found to be the product of individual MTFs.
• The coupled system demonstrated superior performance compared to state-of-the-art all-flexible systems.

Conclusions:

• The novel coupled multifiber technique significantly enhances endoscopic imaging capabilities.
• This technology offers a promising solution for improved observation, display, and photography in medical and industrial fields.
• The findings pave the way for advancements in minimally invasive procedures and industrial inspection.
