A Solution for Ice-Free Sensors

Sensor surfaces that are exposed to weather need to be kept clean so that ADAS and autonomous driving systems can function safely. Ice build-up in cold conditions is of particular concern, but Canatu thinks...

High-Power Broadband Multispectral Source on a Hybrid Silicon Chip

For applications in manufacturing, remote sensing, medicine, military, and fundamental science, an ideal laser would have high output power and a diffraction-limited beam....

Electronically Dimmable Aircraft Windows

That was the challenge posed to Gentex by Boeing. Window shades typically do the job on an airplane, but they’re cumbersome to operate, expensive to maintain, and do little to reflect the...

Terahertz (THz) Radar: A Solution For Degraded Visibility Environments (DVE)

An accurate view of the physical world is frequently vital. For example, rotary wing aircraft pilots must have knowledge of the terrain in order to safely fly...

Testing Multijunction Solar Cell Efficiency

The photovoltaic community is closer than ever to achieving ultra-high multijunction solar cell efficiencies (>50%). Subcells from III–V compound semiconductors are approaching ideal...

Kestrel Wide-Area Sensor Upgrades

In late May, Logos Technologies delivered the first payload upgrade to the Kestrel wide-area sensor, employed on U.S. Navy and Army aerostats in Afghanistan. The new hardware will provide better image...

Low-Power Distributed Jammer Network

The Distributed Jammer Network (DJN) is composed of a large number of tiny, low-power jammers, which are distributed inside a target network and emit radio energy to disrupt its communications. Recent...

Surveillance Systems

New Surveillance System Provides Round-the-Clock Coverage

Logos Technologies has begun delivery of the first two electro- optical/infrared Kestrel wide-area persistent surveillance systems to the U.S. Army for...

Miniature Snapshot Multispectral Imager

Multispectral imagers use an optical device that can separate the colors to obtain the spectral content in the scene. Such an optical device could be a grating or prism, a filter wheel, a diffractive...

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...

Precision Targeting with a Tracking Adaptive Optics Scanning Laser Ophthalmoscope

Adaptive optics (AO) has become increasingly utilized in research ophthalmic diagnostic instruments since their first use nearly ten years ago. Integration of...

Computational Photonics in Laser Communications Through Clouds

This work explored the concept of creating a partially coherent laser beam consisting of an array of spatially overlapping or separated Gaussian beams with possible individual...

Uncooled Tunable LWIR Microbolometers

Uncooled infrared detectors have significant potential capabilities that have been little explored. Micro-machined uncooled detectors with tunable spectral characteristics across the long-wave infrared...

CAT Scanner Provides 3D View Inside Nuclear Weapon Components

The Department of Energy’s (DoE) National Nuclear Security Administration (NNSA) is pursuing a smaller, safer, more secure, and less expensive nuclear weapons complex. Meeting...
