Arnaud Bonin – ‘Membrane wrinkling’

Wrinkling of a thin Kapton membrane. This picture shows the setup of an experiment designed to analyse wrinkles in a thin Kapton membrane. A polygonal shaped membrane is tensioned at its corners, whilst lights of different colours are projected on it to enhance the visualisation of the wrinkles formed. The aim of this experiment is to understand how reflective membranes could be used as the primary mirrors of future space-bound telescopes. The picture was modified by deleting informative number tags which were originally found close to the membrane’s corners.
