Abstract: The invention relates to multicore fiber imaging, such as used in endoscopy. Methods are described for processing images captured with such systems to achieve an improved depth of field image or extract 3D information concerning the images, without requiring the addition of additional optical components. One method for generating an image from light received by an imager via a multiplicity of waveguides includes receiving a digital image containing a plurality of pixels, the digital image including a plurality of regions within it wherein each of said regions corresponds to a waveguide core. Each region includes a plurality of pixels, and a first subset of pixels within each region is defined which at least partly correlates with light having been received at a corresponding core in a first spatial arrangement, the subset including less than all of the pixels within a region. A first image is generated from the first subset of pixels from said regions, combined to form an image over the whole waveguide array. The first spatial arrangement may correspond to a measure of angular dimension of the incident light for that region. In addition to increased depth of field, the modified images provided by the invention allow 3D visualisation of objects, eg. using stereographs or depth mapping techniques.

Abstract: A display system for displaying images on a textured surface. The system includes a display device with a monitor having a screen operable to output light associated with still or animated images. The system further includes an optical block comprising a plurality of optical fibers bonded together to define parallel guide paths. First ends of the optical fibers define a first block surface and second ends of the optical fibers define a second block surface. The first block surface is positioned adjacent the screen to receive and transmit the output light along the guide paths to the second block surface. The system includes a textured display element covering the second block surface for receiving light exiting the second block surface and having a non-planar exterior surface emitting or projecting the received light. The textured display element has a body with an optical index matching that of the optical fibers.
