History & Background / Dossier
Passive EMS is available from TL-10 onwards.
As technology advances, the camera (a basic passive visual sensor) is integrated with other electromagnetic sensors and computer enhancement, until the development of the first crude integrated electromagnetic sensor array at TL-9. This technology is called electromagnetic spectrum sensing or EMS.
The Passive EMS array detects sources of energy. When using the entire EMS array, a simultaneous scan is actually being constructed with four distinct sensor groups.
- A long dipole or wire antenna detect long waves. This antenna can be extended as much as 130 meters. A parabolic dish is used for detecting short waves and microwaves. There is a high density sensor for X-rays and gamma rays. And there is a traditional optical array which covers the infrared, visible and ultraviolet bands.
The pictures generated by these sensors is put direction into computer memory, allowing the picture to be manipulated with ease; it can be instantly shrunk, enlarged or rotated with little loss of definition, and can be compared with another image to detect any change between the two. The picture is of course three dimensional.
