Optics Improvements Prompt Enhanced Component Parameters
For defense and security applications, size matters. So do weight, power, and cost. These four parameters are often referred to as SWaP-C, a key concept that drives the manufacture of defense and security systems, sensors, and optical components.

Measuring NIR Sources for Safe and Accurate 3D Sensing
The rapid adoption of 3D NIR sensing systems requires effective methods to measure the quality, performance, and safety of NIR emitters. NIR wavelengths range from 700 to 1500 nm, and NIR light sources can be used for multiple applications. For example, NIR in the 780-nm range is used and considered safe for eye tracking, and in the 850-nm range is used for night vision in security cameras.

Sensor Uses AI to Obtain Real-Time Images from Satellite Orbit
Researchers at Tokyo Institute of Technology have developed a low-cost star tracker and Earth sensor. The star tracker will be used with microsatellites to handle calibration observations, operation verification tests, and long-term performance monitoring during orbit. The Earth camera will perform image recognition while in orbit using an artificial intelligence system.

Liquid Crystals Could Help Protect Against Laser Pointer Attacks
Liquid crystals could someday be used to help deflect laser pointer attacks on aircraft, regardless of the wavelength used in the attack. To shield pilots from laser attacks, researchers placed a solution of liquid crystals between two 1-inch-square panes of glass.

Millimeter Wave Imager 'Sees' Through Solid Objects
A camera-like device that generates and detects millimeter waves that “see” through solid objects has been built by a University of Delaware (UD) student engineering team. In the future, the device could be useful for military operations and for improving security in airports, schools, restaurants, and other public spaces.
