14' X 14' Portable Planar Near-Field Scanner system (PPNFSS) for the Aegis Array This paer presents an accurate and protable method for RF testing of AN/SPY-1 Antenna Arrays on Navy ships. With four antennas per ship, the usual methods ... George E.Mc Adams,R Romanchuk - Meeting &...
Fast frequency tuning was obtained by rotating a single mirror mounted on a Galvano-optical beam scanner. Consequently, continuous tunability was successfully obtained in the range from 0.7 to 2.6 THz. The THz-wave output exceeded 100pJ/pulse in a broad range from 1.0 to 1.5 THz....
For a 4×4 matrix of 3.88×3.88×19 mm3 LYSO:Ce,Ca crystals one-to-one coupled to a 4×4 array of Broadcom NUV-MT SiPMs, an average CTR of 223 ps (FWHM) was obtained. Conclusion The implemented 16-channel HF electronics are fully functionall and have a negligible influence on the ...
Single crystals of NiTe2were grown by the Te flux method. Mixtures of high-purity Ni powder (99.99%) and Te ingots (99.9999%) were vacuum sealed in the quartz tube. The quartz ampoule was heated to 1050 °C for 10 h, dwelled for 10 h, then slowly cooled to 600 °C with ...
A computer-controlled scanner allows the generation of moving 3D objects that are viewable from any direction in a prototype device at a 25 脳 25 脳 25mmscale, and larger displays that are based on the colloidal dispersion of SHG crystals are envisioned. Our methodology may have important ...
According to certain embodiments, the quadratic approximation can be more accurate than the linear approximation of the first algorithm for at least some temperature values. Because the frequency error over temperature plots for typical crystals are cubic and antisymmetric about a center point, the ...
A piezo scanner with a large range (X, Y: 30 µm, Z: 5 µm, Shimadzu Corporation, Japan) was selected, so that large crystals could be evaluated. The potential and current density corresponded to the time when the AFM images were saved were obtained from the LSV/CV measurement ...
For a long time it has been known that diacetylene monomer single crystals undergo, upon thermal annealing or exposure to high-energy radiation, topochemical solid-state polymerization. From this reaction, polymer chains are formed which have a substantial π-electron delocalization, f...
We constructed a dual-wavelength optical parametric oscillator (OPO) with two K.TP crystals pumped by frequency doubled Nd:YAG laser. Each KTP crystal was set on a Galvano scanner and the angle of each crystal was controlled independently. The OPO has a tunable range from 1300 - 1900 nm, ...
