Abstract

T. Ohzono and co-workers visualize the optical path of the diffused laser beam transmitted through shape-tunable wrinkles with a periodicity in the range of hundreds of micrometers. Without strain, the sample on page 374 shows no wrinkles and no optical diffusion. With uniaxial strain, the surface shows aligned wrinkles and anisotropically diffuses incident light in a manner that depends on the degree of applied strain. This system can be used as a mechanically tunable optical diffuser.
