Optical Distance Measurement at Record-High Speed

  • Magazine Article
  • TBMG-35162
Published 2019-09-01 by Tech Briefs Media Group in United States

Scientists of Karlsruhe Institute of Technology (KIT) and École Poly-technique Fédérale de Lausanne (EPFL) have reported that they achieved the fastest distance measurement attained so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. Potential applications include real-time 3D cameras based on highly precise and compact LIDAR systems.

Software Enables Robots to Self-Right After Overturning

  • Magazine Article
  • TBMG-35137
Published 2019-09-01 by Tech Briefs Media Group in United States

The Advanced Explosive Ordnance Disposal Robotic System (AEODRS) features a modular open systems architecture that enables the robot to be self-righting after a fall. The self-righting ability is extended to robots with a greater number of degrees of freedom (joints).

Detecting Chemical Weapons Using Fourier Transform Infrared Spectroscopy

  • Magazine Article
  • TBMG-35165
Published 2019-09-01 by Tech Briefs Media Group in United States

Chemical Warfare Agents (CWA) are a class of Weapons of Mass Destruction (WMD) designed to kill and injure humans through exposure to extremely toxic chemicals. In addition to CWA many chemicals used by industry, often referred to as Toxic Industrial Chemicals (TICS) can potentially be used by terrorists as weapons.

Integration of Adaptive Optics Into High-Energy Laser Modeling And Simulation

Aerospace & Defense Technology: September 2019

  • Magazine Article
  • 19AERP09_08
Published 2019-09-01 by SAE International in United States

Implementing adaptive optics can substantially increase the effective range of high energy lasers used in directed energy weapons systems.

The U.S. Navy is constantly predicting future threats and contemplating new weapon technologies to counter them. One of those technologies is directed-energy (DE) weapons. Conventional weapons rely on the kinetic energy of projectiles. High-energy lasers (HELs), one type of directed-energy weapon, work in a fundamentally new way, using electromagnetic radiation to damage or destroy enemy assets.

Real-Time Heuristics and Metaheuristics for Static and Dynamic Weapon Target Assignments

  • Magazine Article
  • TBMG-34872
Published 2019-08-01 by Tech Briefs Media Group in United States

Projectile weapons have been a consistent threat of hostilities throughout history. Military advantage has always been aided by the capacity to inflict damage from a distance. In the 20th century, missile technology advanced to the point that an adversary had the potential to attack a protected asset from great distances. To neutralize this stand-off threat, the concept of air defense evolved. However, as the ability to reduce a missile threat increased, so, too, did the quantity and quality of missiles available, and research into the effective allocation of air defense resources emerged.

Nominal High-Altitude Electromagnetic Pulse (HEMP) Waveforms

  • Magazine Article
  • TBMG-34870
Published 2019-08-01 by Tech Briefs Media Group in United States

Even before the Trinity nuclear test in July of 1945, physicists predicted a transient electromagnetic signal would be caused by high-energy photons released from the detonation interacting with the air around the detonation. Predictions of these signals were difficult to make due to the complexity of the physics unleashed by the detonation.
