Windowed defocused photographic speckle vibration measurement
Jose M. Diazdelacruz
The out-of-plane vibration of a rough surface causes an in-plane vibration of its speckle pattern when observed with a defocused optical photographic system. If the frequency of th…
Quantum Information Engines with Many-Body States attaining optimal Extractable Work with Quantum Control
J. M. Diazdelacruz, M. A. Martin-Delgado
We introduce quantum information engines that extract work from quantum states and a single thermal reservoir. They may operate under three general conditions: i/ Unitarily Steered…
Adaptive Aperture Defocused Digital Speckle Photography
Jose M. Diazdelacruz
Speckle photography can be used to monitor deformations of solid surfaces. The measuring characteristics, such as range or lateral resolution depend heavily on the optical recordin…
Multi-windowed defocused speckle photographic system for tilt measurement
Jose M. Diazdelacruz
Defocused speckle photography has long been used to measure rotations of rough surfaces. This paper explains how, by adding a suitably perforated mask, some measurement properties,…
