Sensors

Sensors are devices which analyze or detect distant or remote objections.

Known types

Electromagnetic sensors

IR

Infrared light is, fundamentally, light with a longer wavelength than visible light. It is emitted by all bodies based upon their temperature. IR imaging can be both active and passive in application: actively, it can emit IR light which is reflected back to the source and received via an optical sensor.

GRADAR

Gravitic detection and ranging technology is relatively new and much is still being learned about the effects of elementary particles upon various metamaterials. To date, rudimentary GRADAR systems which use confined spheres of ferrofluids have had some success in analyzing streams of gravitons.

LED

Light emitting diodes have traditionally been used as their name would infer: to emit light. The exact same principles used in their design also allows them to act as photodiodes; that is, a device which detects light (of specific wavelengths) and energizes a circuit, not unlike a solar cell.

LED sensors have remained relevant because they require no power to function and are passive.

LIDAR

Light detection and ranging technology uses aimed, coherent beams of light (typically lasers) to detect or inspect objects. It can also be used for more accurate ranging of objects. Modern examples of this technology have a very high resolution and can be used from great ranges, despite light lag.

MADAR

Mass detection and ranging is accomplished in a variety of ways, some methods more precise than others, but offering different trade-offs. The two more common are a gravity seeking magnetically confined mechanical sensor and a more precise method using hard vacuum and a gyroscope.

The latter form operates by detecting the shift of a magnetic field due to external forces.

MAGNUS

Magnetic navigation and unmasking sensors are an arrangement of superconductors which react when exposed to changes in ambient magnetic fields. This mass detection system is very precise and is capable of relaying a great deal of information to operators who understand it's calibration and use.

RADAR

Radio detection and ranging technology is an ancient, but still useful, technology. It has a much wider field than LIDAR, but it's accuracy is not quite so refined. Still, it sees widespread use in civilian and military applications due to it's cheap cost and practical effectiveness in all environments.
