Laser light diffracted by a hologram, microscopic details from a man-made fabric and photos from the deepest tunnels of the London Underground are among an array of stunning images which have been put online following the annual photographic competition at the University of Cambridge Department of Engineering.

The competition aims to show that engineering is not only about fixing machines and building bridges, but involves everything from studying objects and processes in microscopic detail, to building towering structures. The winning images can be viewed online from today via the University's website, www.cam.ac.uk, where they can be accessed alongside dozens of other entries.
