System Makes Airport Surface Traffic More Efficient

Researchers are attempting to improve the control tower software system using mathematics and optimization techniques. (Photo: ThinkStock) Researchers have developed an optimization system that identifies the optimal timing and taxiing sequences for runway use by a given aircraft. It plans detailed taxiing routes, recommends new routes automatically, and responds to a continuous stream of updated information. The model takes into account the basic rules and physical restrictions that apply at all airports, such as safety zones around turning aircraft and one-way taxiing routes.

Researchers Test Galaxy-Seeking Robots

A telescope project from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) will use a planned array of 5,000 galaxy-seeking robots to produce a 3D map of the universe. Dubbed ProtoDESI, the scaled-down, 10-robot system will help scientists achieve the pinpoint accuracy needed to home in on millions of galaxies, quasars, and stars with the Dark Energy Spectroscopic Instrument (DESI).

SLED-Based Broadband Near-Infrared Source

Avo Photonics (Horsham, PA) design, development, and manufacturing, was commissioned by Luxmux Technology Corporation, to develop and manufacture a solid-state, broadband, continuous emitter for use with their line of miniature integrated spectrometers. The emitter combines the outputs of multiple super-luminescent LEDs (SLEDs) into a polarization-maintaining single-mode fiber. Such an accomplishment required collimating multiple beams and achieving collinearity to an overlap of 700 um and pointing to within 250 urad. The result is a >100 mw, fiber-coupled source with continuous emission over the 1250 – 1750 nm band. To learn more, click here.

Short Pulse Seed Laser Diode Driver

Analog Modules, Inc. (Longwood, FL) recently released its short pulse seed laser diode driver, Model 766. The Model 766 offers user-adjustable pulse width capability as low as 150ps up to 1ns for driving 14-pin butterfly packaged laser diode modules at output currents up to 1.1A. Applications include seeding fiber lasers for materials processing, time-resolved spectroscopy, LIDAR and others. The driver circuitry operates from a single 5V power source. All other needed voltages are generated on the board by high efficiency switching power supplies. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 3A and voltage capability of 4.2V.

Core Alignment Fusion Splicer

Furukawa Electric (Tokyo, Japan) and OFS (Norcross, GA) recently introduced the FITEL S179 Hand-Held, Core Alignment Fusion Splicer. The FITEL S179 Fusion Splicer can be used on all Metro, LAN and FTTx fibers, including ultra-bend insensitive fibers. The FITEL S179 Fusion Splicer’s large-capacity battery system allows 200 splicing cycles (splicing/heating) in one charge. A 4.3-inch wide LCD screen with touch panel offers easy and intuitive operation and a proportionately wide splicing chamber makes optical fiber easier to load. For improved visibility in low-light conditions, 3 +1 LED lights illuminate the entire splicing chamber. To learn more, click here
