Transparent Ceramics for High-Energy Laser Systems

When a high-energy laser (HEL) beam transmits through a window material, a part of the laser energy is absorbed by the material and causes optical aberrations. This absorbed energy results in material heating in the local exposed region, changing its refractive index based on the material’s thermo-optic coefficient, thermal expansion coefficient, and stress optic coefficient. These changes result in beam distortion and loss of output power, measured as optical path distortion (OPD), which has a severe impact on system performance.

Fabrication of Novel Transparent PMMA Composites for Optical Tagging

The emerging threats caused by improvised explosive devices (IEDs) have drastically increased concerns about soldier survivability. The ability to identify “friend vs. foe” of any approaching vehicles clearly, quickly, and from a distance, is invaluable to ensure a soldier’s safety, as well as critical to providing protection of facilities at strategic locations. The current state-of-the-art uses externally applied coatings or markings onto vehicles that are not seen in the visible light spectrum, yet are detectable with the use of an ultraviolet (UV) or infrared (IR) interrogation device. However, coatings can wear off or wash off, and are susceptible to being counterfeited or tempered.

Encryption Processor

Enova Technology Corp. (San Jose, CA) has announced its ninth-generation X-Wall DX processor, a real-time hardware encryption device. The processor encrypts all USB mass storage class (MSC) devices at USB 2.0 wire speed with NIST (National Institute of Standards and Technology), and CSE (Communication Security Establishment) certified hardware for AES ECB and CBC mode of operation. Entire data-at-rest, including MBR (Master Boot Record) and Boot Sectors, are AES-encrypted. The device features FIPS 140-2 certification numbers 1471 and 1472 for the X-Wall MX-256 and X-Wall MX-256C crypto modules, respectively.
