Beam shaping - the ability to engineer phase and amplitude of massive massless particles has long interested scientists working on communication, imaging foundations quantum mechanics. In light optics, electromagnetic waves (photons) can be achieved using techniques that include, but are not limited to, direct manipulation beam source (as in X-ray Free Electron Lasers (XFELs) Synchrotrons), def...
We propose and experimentally demonstrate an interferometer for femtosecond pulses with spectral bandwidth about 100 nm. The scheme is based on a Michelson interferometer with a dispersion compensating module. A diffractive lens serves the purpose of equalizing the optical-path-length difference for a wide range of frequencies. In this way, it is possible to register high-contrast interference ...
The paper presents the experimental evaluation of 94 GHz CW-FM Radar that can be configured as a Ground Based SAR (Synthetic Aperture Radar) for high resolution imaging and deformation control. This system has been designed to obtain and analyze data of deformations on different types of bodies, being able to detect range changes of the order of micrometers. After indoor testing and validation ...
