Portable electro-optic device for performing serviceability check on IR guided missiles

Electro-optically guided weapons are the most potent and widely used munitions on land-based, aerial and ship-borne platforms because of their proven precision strike capability. Two such guided weapon categories include the IR guided surface-to-air and air-to-air missiles and laser guided bombs and missiles. The efficacy of the mission is critically dependent on the successful deployment of the weapon. This not only necessitates that periodic functionality check be carried out on these weapons, it should also be possible to perform functionality check also known as serviceability check even after they are strapped on to the launch platform. Serviceability check in the strap-on condition ensures a much higher hit probability. This paper presents the design and development of a portable electro-optic device that generates IR signatures in 3–5-μm band having the desired amplitude and spectral shape to match the IR signatures of target aircraft. A prototype was built using the proposed concept. The prototype was characterized in terms of its output amplitude and wavelength spectrum. The prototype was used to perform serviceability check on IR seekers of foreign origin. Test results are presented in the paper.     

MxDC and MxLIVE: software for data acquisition,information management and remote access to macromolecular crystallography beamlines

An integrated computer software system for on‐site and remote collection of macromolecular crystallography (MX) data at the Canadian Light Source (CLS) is described. The system consists of an integrated graphical user interface for data collection and beamline control [MX Data Collector (MxDC)] which provides experiment‐focused control of beamline devices, and a laboratory information management system [MX Laboratory Information Virtual Environment (MxLIVE)] for managing sample and experiment information through a web browser. The system allows remote planning and transmission of sample and experiment parameters to the beamline through MxLIVE, on‐site or remote data collection through MxDC guided by information from MxLIVE, and remote monitoring and download of experimental results through MxLIVE. The system is deployed and in use on both MX beamlines at the CLS which constitute the Canadian Macromolecular Crystallography Facility.     

Integrated Genetic Analysis Microsystems

The advent of integrated microsystems for genetic analysis allows the acquisition of information at unprecedented length and time scales. The convergence of molecular biology, chemistry, physics, and materials science is required for their design and construction. The utility of the microsystems originates from increased analysis speed, lower analysis cost, and higher parallelism leading to increased assay throughput. In addition, when fully integrated, this technology will enable portable systems for high-speed in situ analyses, permitting a new standard in disciplines such as clinical chemistry, personalized medicine, forensics, biowarfare detection, and epidemiology. This article presents an overview of the recent history of integrated genetic analysis microsystems with an emphasis on materials aspects, and provides a perspective on current developments and future prospects.

Theoretical model of a planar waveguide refractive index sensor assisted by a corrugated long period metal grating

A theoretical model of a novel planar integrated refractive index sensor based on surface plasmon-polariton (SPP) excitation with a corrugated metal long period grating (LPG) is presented and comprehensively investigated. The main principle of the operation this device is based on co-directional energy transfer by means of a corrugated metal LPG between a p-polarized guided mode propagating in a waveguide layer and the SPP propagating a metal layer separated from the waveguide layer by a buffer. The corrugated LPG is engraved in the metal layer in contact with the sensed medium. The power transmitted through the LPG in the guided mode serves as an input signal for an interrogation unit. This device is free from any moving parts and can be simply integrated into any planar waveguide system. Our sensor simulations are based on the local-normal-mode transfer matrix method and performed in telecom wavelength range.

The comparison between the numerical results obtained with 54 and 12-parameter edge element method shows that the present approach is more accurate and efficient.
