A high peak power density and low mechanical stress photonic-band-crystal (PBC) diode laser array based on non-soldered packaging technology is demonstrated. The consists of the PBC bars with small fast axis divergence angles. Meanwhile, we design structure that realizes stacking 10 in vertical direction. In experiment, about 1.75 times conventional when same total obtained. 292.2 W, “smile” ef...
Does the language you speak affect how you think about the world? This question is taken up in three experiments. English and Mandarin talk about time differently--English predominantly talks about time as if it were horizontal, while Mandarin also commonly describes time as vertical. This difference between the two languages is reflected in the way their speakers think about time. In one study...
In active-matrix liquid crystal displays with large pixel array and large number of graylevels, the luminance of a pixel depends on the luminance of the rest of the image. This artifact known as crosstalk is caused by parasitic phenomena in the active-matrix array. When interpreting high information content medical images with subtle features and structured background, crosstalk can a ect image...
We consider the cross-correlation of a Costas array with its image under a horizontal and/or a vertical flip. We propose and prove several bounds on the maximal cross-correlation and on its value at the origin, for both general Costas arrays and for algebraically constructed ones.
A 664 x 664 element Active Pixel image Sensor (APS) with integrated analog signal processing, full frame synchronous shutter and random access for applications in star sensors is presented and discussed. A thick vertical diode array in Thin Film on CMOS (TFC) technology is explored to achieve radiation hardness and maximum fill factor.
Approaches for instantaneous passive source localization using a towed horizontal receiver array in a random range-dependent ocean waveguide are examined. They include: (1) Moving array triangulation, (2) array invariant, (3) bearings-only target motion analysis in modified polar coordinates via the extended Kalman filter, and (4) bearings-migration minimum mean-square error. These methods are ...
This paper describes the design of LeviTABLE, an electromagnetic controlled topographical display device. The electromagnets control the movement and displacement of an array of vertical rods. The height of these rods represents individual points of elevation in a landscape. We describe the iterative design and implementation of LeviTABLE, discuss design issues and suggest further research dire...
We demonstrate, both theoretically and experimentally, a pseudo-random, two-dimensional optical phased array (OPA) concept based on tandem injection locking of 64-element vertical cavity surface emitting laser (VCSEL) arrays. A low cavity-Q VCSEL design resulted in an injection locking optical power of less than 1 μW per VCSEL, providing large OPA scaling potential. Tandem injection locking of ...
The Grande array as main part of the KASCADE-Grande experiment consists of 37×10 m scintillation detectors spread over an area of 700×700 m. Grande enables triggers and reconstruction of primary cosmic rays in the energy range of ∼ 3 · 10eV to 10eV. The detectors and the shower size (i.e.: total number of charged particles) reconstruction accuracies are discussed. The KASCADEGrande set-up allow...
Due to the extremely low power, GPS signal can be easily affected by interferences. In this paper, from the point of adaptive array processing, we review the existing spatial and space-time interference suppression methods which attempt to mitigate interferences before the GPS receiver performs correlation. These methods comprise self-coherence restoral technique based on the nature of GPS sign...
