A Flexible Fibrescope, using Static Scanning

  title={A Flexible Fibrescope, using Static Scanning},
  author={Harold H. Hopkins and Narinder S. Kapany},
AN optical unit has been devised which will convey optical images along a flexible axis. The unit comprises a bundle of fibres of glass, or other transparent material, and it therefore appears appropriate to introduce the term ‘fibrescope’ to denote it. An obvious use of the unit is to replace the train of lenses employed in conventional endoscopes. The existing instruments of this kind, for example, cystoscopes, gastroscopes and bronchoscopes, etc., consist of a train of copying lenses and…

Wide-angle lens for miniature capsule endoscope

A novel miniature lenses which has a wide angle of field of view and a good quality of imaging is designed which will help medical professionals to examine digestive diseases unclearly and ambiguously.

Side-view holographic endomicroscopy via a custom-terminated multimode fibre.

An all-fibre probe with an engineered termination that reduces compression and damage to the tissue under investigation upon probe insertion is designed and shown that its focusing ability also benefits from a higher numerical aperture, resulting in imaging with increased spatial resolution.

Design of wide-angle lenses for wireless capsule endoscopes

Tolerance analysis shows that the proposed novel design for miniature lenses with a wide-angle field of view and good imaging quality is feasible for manufacture, and consistent with the finished prototype.

Transparent Fibres for the Transmission of Optical Images

An account is given of earlier experiments [2] in which a flexible bundle of fine glass fibres was successfully used for the transmission of optical images. Some more recent photometric and other

Rigid ureteroscopes with fiberoptic imaging bundles: features and irrigating capacity.

The more recent small ureteroscopes allow an adequate irrigant flow while accepting working instruments suitable for a variety of procedures, and seem to be ideal for diagnostic u reteroscopy, as they are quick and easy to use, not even requiring Ureteral dilation.

Distortion improvement of capsule endoscope image

Distortion exists in the present capsule endoscope image resulting from the confined space and the wide-angle requirement [8]. Based on the previous two lens works, the optimal design had obtained

Fibre optic scrambling in light microscopy: A computer simulation and analysis

Computer simulations are used to investigate several parameters affecting light randomization in curved optical fibres in order to further the theoretical basis for scrambler design.

The Invention Of Fibre Optics Imaging By Television Pioneer John Logie Baird

Television pioneer John Logie Baird, a Scot from Helensburgh near Glasgow, described in his 1928 British patent No. 285,738 a honeycomb bundle of hollow metal tubes or thin solid rods of various
