advanced tactical air reconnaissance system
An aerial reconnaissance system that can transmit, in near real time, image data recorded by IR and visual-spectrum sensors, providing day, night and foul-weather intelligence.
aerial reconnaissance
The use of optical or electronic recording systems to extract information from the terrain, while aloft, for reconnaissance applications.
luminaire
A complete unit containing a light source, globe, reflector, housing, socket and other necessary components for lighting.
angular magnification
->
magnification
The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of...
ATARS
advanced tactical air reconnaissance system
contact microradiography
The radiography of small objects having detail too fine to be seen by the unaided eye. The resulting negative, when optically enlarged, can be examined.
erect image
An image, real or virtual, whose spatial orientation is identical to that of the object. The image obtained at the retina with the assistance of an optical system is said to be erect when the...
haze
An aggravated form of fog in a polished surface caused by the scattering of light. The defects causing haze are larger than those causing fog, but singly are not large enough to be seen by the...
lateral magnification
->
magnification
The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of...
longitudinal magnification
->
magnification
The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of...
macroscopic
Sizable enough to be perceived by the unaided eye.
magnification
The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of...
micromanipulator
A device that provides means for accurately moving minuscule tools over the surface of a microscopic object. The motion precision of a micromanipulator exceeds that of the unaided human hand....
microscopic
Characteristic of an object so small in size or so fine in structure that it cannot be seen by the unaided eye. A microscopic object may be rendered visible when examined under a microscope.
microscopy
Microscopy is a scientific technique that involves the use of microscopes to observe and study objects that are too small to be seen with the naked eye. Microscopes are instruments that magnify and...
multimodal vision-language models
Multimodal vision-language models (MVLMs) are advanced AI systems designed to understand and process information that combines both visual and textual data. These models are capable of interpreting...
QSR
quick strike reconnaissance
rotating mirror scanner
Developed for use in military reconnaissance systems, it consists of a polygonal mirror, drive motor, interface between motor and mirror, and control electronics. Also used in broadband video...
scintillation crystal
A scintillation crystal, also known simply as a scintillator, is a material that emits light when it interacts with ionizing radiation such as gamma rays, x-rays, or charged particles. The emitted...
stereoscopic radius
The maximum distance at which the stereoscopic effect may be observed. With respect to the unaided human eye, it has been estimated at about 1500 ft.
unmanned aerial vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot onboard. UAVs are remotely controlled or autonomously operated, and they can be used for various...
