I was interested in the intraoperative endoscopic approach of visualizing the extrahepatic biliary system in the late 50s, but I was ignorant about optics and instrumentation. A lateral-view cystoscope with a distal electric globe introduced in large dilated ducts produced an extremely dim image. The optical system in use was developed by Nietze before the turn of the century and had improved little since its introduction. The light (image) loss was more than 90%, resulting in poor light and… Expand
The role of the surgeon in the evolution of flexible endoscopy
TLDR
This review was initiated by the SAGES Flexible Endoscopy Committee to chronicle the role of the surgeon in the development and introduction of flexible endoscopy into clinical practice, historically and in contemporary surgery. Expand
Rigid chip-on-the-tip endoscope for rhinosurgery and diagnosis
TLDR
A new prototype endoscope using the “chip-on-the-tip” technology, with advantages compared to the conventional Hopkins endoscope, connected to a standard camera head, are the smaller size, weight and the necessity of only one cable instead of two, allowing easy handling. Expand
Exploiting multimode waveguides for pure fibre based fluorescence imaging
There has been an immense drive in modern microscopy towards miniaturisation and _bre based technology. This has been necessitated by the need to access hostile or difficult environmentsExpand
HAROLD HORACE HOPKINS: A SHORT BIOGRAPHY
TLDR
Harold Horace Hopkins (Fig. 1) was born in 1918 in Leicester, UK and he won a scholarship to University College, Leicester and he graduated in physics and mathematics three years later. Expand
Exploiting multimode waveguides for pure fibre-based imaging
TLDR
A novel approach is presented by utilizing disordered light within a standard multimode optical fibre for lensless microscopy and optical mode conversion and showing how such control can realize a new form of mode converter and generate various types of advanced light fields such as propagation-invariant beams and optical vortices.

Optical manipulation, beam-shaping and scanner-free bright-field and dark-field imaging via multimode optical fibre
We present a powerful approach towards full understanding of laser light propagation through multimode optical fibres and control of the light at the fibre output. Transmission of light within aExpand
