15 صفحه اولA Review of Speckle Photography and Interferometry
Speckling is an interference effect invariably present when highly coherent light is scattered by the different elements of an optically rough surface (roughness ~ " J '" = wavelength). Speckle patterns appear everywhere in space, but interest centres on the image a nd Fourier transform planes. The lateral dime n sion of i ndiv idual speckles is determin ed by the interference of waves from the...
متن کاملAdaptive aperture defocused digital speckle photography.
Speckle photography can be used to monitor deformations of solid surfaces. Its measuring characteristics, such as range or lateral resolution, depend heavily on the optical recording and illumination setup. I show how, by the addition of two suitably perforated masks, the effective optical aperture of the system may vary from point to point of the surface, accordingly adapting the range and res...

Laser speckle photography for surface tampering detection Citation
It is often desirable to detect whether a surface has been touched, even when the changes made to that surface are too subtle to see in a pair of before and after images. To address this challenge, we introduce a new imaging technique that combines computational photography and laser speckle imaging. Without requiring controlled laboratory conditions, our method is able to detect surface change...
