Dataset on raindrop size distribution, raindrop fall velocity and precipitation data measured by disdrometers and rain gauges over Peruvian central Andes (12.0°S).

This dataset includes data obtained at the Atmospheric Microphysics and Radiation Laboratory (LAMAR) of the Huancayo Observatory (12.04° S, 75.32° W, 3313 m ASL).

Fourier transform acousto-optic imaging with a custom-designed CMOS smart-pixels array.

We report acousto-optic imaging (AOI) into a scattering medium using a Fourier Transform (FT) analysis to achieve axial resolution. The measurement system was implemented using a CMOS smart-pixels sensor dedicated to the real-time analysis of speckle patterns. This first proof-of-principle of FT-AOI demonstrates some of its potential advantages, with a signal-to-noise ratio comparable to the one obtained without axial resolution, and with an acquisition rate compatible with a use on living biological tissue.

Design and implementation of a page-oriented "holographic" memory based on a Lippmann architecture.

Optical data storage inspired by Lippmann interference color photography was proposed a long time ago as an alternative to holographic memories. Very high capacities were predicted for a page-oriented approach with wavelength multiplexing, but, up to now, such an architecture has never been implemented. Based on simple conception rules, we build such a page-oriented Lippmann data storage system.

Balanced homodyne detection of Bragg microholograms in photopolymer for data storage.

Wavelength multiplexed holographic bit oriented memories are serious competitors for high capacity data storage systems. For data recording, two interfering beams are required whereas one of them should be blocked for readout in previously proposed systems. This makes the system complex.
