Data for "High resolution air-clad imaging fibers"

The data supporting the results presented in the paper "High resolution air-clad imaging fibers". This body of work is designed to provide an indication of the imaging performance of a novel, high resolution imaging coherent fibre bundle fabricated in the University of Bath's Centre for Photonics and Photonic Materials' facilities. Traditionally, the imaging fibres such as those used in medical endoscopes consist of solid doped and undoped silica glass. The novelty of our design is in having the cladding that is comprised of air-filled silica capillaries, achieving a cladding index close to that of air. This increase in index contrast with the cores (still solid doped silica) provides a higher numerical aperture waveguide. As a result, the light is better confined to the cores, and higher resolution, or a wider operational bandwidth, can be achieved.

Documentation

Data collection method:

For the images: Supercontinuum light sources were used as the excitation source throughout all visible and IR imaging experiments. Lenses with NA greater than 0.5 were used for all imaging experiments. A silicon camera and bandpass filters were used to obtain 500-1000 nm wavelength images. a short wave infra-red camera was used from 1000-1600 nm wavelength. For the spreadsheet data: This is loss data that was obtained using the cutback method by coupling a 633 nm helium neon gas laser into a group of 100 or more cores of the imaging fibre.
