Broadband Waveguided Light Sources
In recent years, broadband fiber interferometers have become very popular as basic instruments used in optical low-coherence reflectometry for diagnostics of fiber and integrated optics devices or in optical coherence tomography (OCT) for imaging applications in the biomedical field. The longitudinal resolution of such instruments is inversely proportional to the optical bandwidth of the light ...
متن کاملA Novel Technique for Broadband SVD
The singular value decomposition (SVD) is a very important tool for narrowband adaptive sensor array processing. It finds application in areas as diverse as high resolution direction finding, stabilised adaptive beamforming and blind signal separation [1,2]. The SVD decorrelates the signals received from an array of sensors by applying a unitary matrix of complex scalars which serves to modify ...
متن کاملNew frequency translation technique for FM-CW reflectometry.
In broadband microwave reflectometry, coherent detection is widely used to obtain the phase information and to improve the systems sensitivity, both in diagnostics measuring the electronic density profile and plasma fluctuations. Coherent detection uses a translated version of the probing signal to guarantee a stable intermediate frequency. Here, a novel technique to generate the frequency tran...
متن کاملARBRES: Light-Weight CW/FM SAR Sensors for Small UAVs
This paper describes a pair of compact CW/FM airborne SAR systems for small UAV-based operation (wingspan of 3.5 m) for low-cost testing of innovative SAR concepts. Two different SAR instruments, using the C and X bands, have been developed in the context of the ARBRES project, each of them achieving a payload weight below 5 Kg and a volume of 13.5 dm3 (sensor and controller). Every system has ...
متن کاملBroadband polygonal invisibility cloak for visible light
Invisibility cloaks have recently become a topic of considerable interest thanks to the theoretical works of transformation optics and conformal mapping. The design of the cloak involves extreme values of material properties and spatially dependent parameter tensors, which are very difficult to implement. The realization of an isolated invisibility cloak in the visible light, which is an import...
