(a) Photographs of blast injury dosimeters using 3D PhCs made by IL before and after exposure to blast waves having peak overpressures of 655 and 1,090 kPa. The SEM images allow identification of changes in the structural features of the blast injury dosimeter after the shock. Reproduced with permission.30 Copyright 2010, Elsevier Inc. (b) Photograph of a transparent PhC shows colors at elevated temperature and its temperature-dependent optical scattering spectra. Depending on a viewing angle, different colors are observed from the PhC at 100 °C, as shown by the spectra below. Reproduced with permission.320 Copyright 2009, American Institute of Physics.
