I think you might be mistaken. Light travels through a fiber cable not 'straight' through along its centerline, but by reflecting many times off the sides of its interior. The walls of the cable serve as an incredibly long, flexible mirror (at very obtuse angles glass/air surfaces reflect light with incredible efficiency - look at an SLR's pentaprism - no mirrors, but the image you get is very clear). You can transmit light signals, but I don't believe you'd get any sort of cohesive image on the other end. The Polaroid backs work in a "one strand=one image point" fashion. You still need an optical system (lens/pinhole) to form the actual image. Simon
