This photograph shows rods of glass stacked in a hexagonal arrangement and held in resin. It is a previous iteration of the imaging fibres currently being constructed at the University of Bath, and was made using identical glass rods that contain light-guiding regions (cores) of different sizes. Inside such fibres, each core carries information about an image like individual pieces in a puzzle, and is surrounded by different neighbours. The difference in core size between neighbours reduce the amount of light that can spread across the structure, which can blur the resultant image.
The structure is placed on top of a black and white image of dots and illuminated by a light box. The pieces of rod are very short, and so the image underneath can be seen through them. The different neighbours in this stack can distort the image.
The image was taken using a regular digital camera, and thanks go to Harry Wood for his neatly polished imaging fibre resin puck.
