Laser-based wireless power transmission (LWPT) technology

Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which …

DARPA ENVision developing next-generation Night Vision Goggles (NVGs) which are compact, multi-band, and wide-FOV

For decades U.S. warfighters have benefitted from advanced night-vision technology, allowing pilots to fly low-level missions on pitch-black nights and ground forces to conduct operations against adversaries in the dark. Traditional Night Vision Goggle (NVG) systems provide the wearer with enhanced visibility in low-light conditions by exploiting the natural near-infrared …

Nano-opto-electro-mechanical systems (NOEMS)

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems)  integrate sensors and actuators on microelectronic circuitry and enabling these products, awareness of the surroundings in …

Infrared detectors enable Night Vision Devices, Robotic servicing mission to military missile tracking

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it.  This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Some examples of remote sensing are special cameras on satellites and airplanes taking …

Thermal imaging camera technologies image hidden targets from far in complete darkness through fog or smoke

Thermal vision cameras make pictures or video from heat, not visible light. Heat (infrared thermal radiation) and light are both parts of the electromagnetic spectrum. Thermal cameras detect more than just heat. Heat vision cameras detect the tiny differences in heat, even as small as 0.01° Celsius.   All objects warmer than …
