Millimeter-wave center of curvature test for a fast paraboloid.
We describe a technique for measuring the surface profile of a radio telescope with a fast paraboloidal primary. The technique uses a sensor, at the center of curvature of the primary, consisting of a millimeter-wave source and an array of receivers to measure the field in the caustic. The sensor is mounted on the telescope enclosure and it moves with the telescope, so the measurements can be u...
متن کاملTomographic reconstruction of designer free-electron wave packets.
We review the generation and tomographic reconstruction of designer electron wave packets, that is, electron wave packets with a tailored momentum distribution in the continuum. Generation is accomplished by means of multiphoton ionization of an atomic prototype using polarization-shaped femtosecond laser pulses. Both the electronic structure of the neutral and interference of matter wave packe...
متن کاملLamb Wave Tomographic Reconstruction Using Various MART Algorithms
Structural Health Monitoring (SHM) system requires a fast and accurate algorithm for defect detections in the large structures like aircraft skins for which Lamb wave tomography (LWT) appears to be very powerful technique, as their propagation properties depend on the thickness and the mechanical properties of the material. Projection data is collected by electronically scanning an array of ult...
متن کاملTomographic Reconstruction of the Ionospheric Electron Density in term of Wavelets
Ionospheric tomography is a method to investigate the ionospheric electron density in two or three dimensions. In this study, the function-based tomographic technique has been used for regional reconstruction of a 3D tomographic model of the ionospheric electron density using the GPS measurements of the Iranian Permanent GPS Network. Two-dimensional Haar wavelets and empirical orthogonal functi...
