Cavity Ring-Down spectroscopy (CRDS) is a newer IR absorption-based technique made possible by the use of tunable pulsed lasers. Rather than using a broadband (blackbody) emitter as is done with traditional IR techniques, a pulsed laser is tuned across wavelengths into an optical cavity.
Ellipsometry measures the amplitude ratio and the phase difference between polarized light reflected from the surface of a film and determines the refractive index or thickness by fitting the experimental data to an optical model that represents an approximated sample structure.
Synthetic Aperture Radar images are a powerful tool for studying the Earth’s surface. They are radar signals generated by an imaging system mounted on a platform such as an aircraft or satellite. As the platform moves, the system emits sequentially high-power electromagnetic waves through its antenna.
Introduced here is the formal PTZ Search Problem. In the PTZSP, a fixed PTZ camera starts at a given PTZ position and must move through the continuous 3D space of PTZ coordinates to detect as many objects of interest as possible as quickly as possible.
Distributed fiber sensors are a powerful tool for structural health monitoring and environmental sensing due to their ability to remotely monitor the strain at 1,000s of locations using low-cost optical fiber.
As weapon system designers continue to innovate for the defense of the nation, the Air Force Test Center must advance the test capabilities available to develop and prove the superiority of those systems...
Garmin’s commercial-off-the-shelf (COTS) G3000 open architecture supports integration with a wide range of mission equipment including military sensors, helmet mounted displays, and advanced electrically scanned radar systems.
Onboard electronics continue to evolve rapidly. Components are smaller. Systems are more complex. The sophisticated electronics components that make up modern vehicles require precision heat dissipation for...
Extremely light and well-suited for operations in contested environments, nearly silent, and with a flight time up to 25 minutes, the combat-proven, pocket-sized Black Hornet PRS transmits live video and HD still images back to the operator.
