This option measures loss of optical wave guides by scanning a fibre optic probe and photodetector down the length of a propagating streak to measure the light intensity scattered from the surface of the guide. The assumption is that at every point on the propagating streak the light scattered from the surface and picked up by the fibre is proportional to the...
