SENSORS
This is a collective name for a variety of devices for gathering data about
electromagnetic radiation and particles and for chemical, biological
and medical analysis. External sensors are attached to the outer hull
of a Starship.
Among them are navigational sensors which determine the ship's position and
velocity and scientific sensors for astronomical observation,
planetary surface analysis and remote life form analysis. Internal
sensors are used to control life support and detect hazardous
environmental conditions as well as to track potential intruders.
Finally, sensors are also included in tricorders and other hand-held
devices which can perform similar tasks; however, their range is
limited.
Real world sensor systems will soon accomplish the basic functionality
shown in Star Trek. However, subspace sensor beams travelling faster
than light are as utopian as warp drive. The Ferengi ship attacking
the U.S.S. Stargazer did not have FTL sensing capability, so Picard
could fool its sensors with his famous "Picard Manoeuvre" (TNG: "The
Battle"). Irrespective of the signal speed, there is a severe problem
with long-range sensors.
At short distances, with something like a normal photographic lens, it
is no problem to show an approaching Starship at great detail.
Collecting light from a few light years away, however, with a "super
tele lens" would mean waiting for random photons coming from that
direction - it's impossible to form an image, let alone a sharp image
in real time this way. That's why we must find our explanation in
subspace (again). Subspace obviously allows the transmission of
electrical signals over long distances without significant losses, so
it could be a "subspace image" of the remote ship.
Duotronics Sensors
Revolutionary computer
technology invented by Dr. Richard Daystrom in 2243 as used in The
Ultimate Computer [TOS]
Duotronics became the
basis of the computers used aboard all Federation Starships for over
80 years, including the main computers aboard the Enterprise. The ship
also used duotronic elements in its sensor arrays - Trials and
Tribble-ations [DS9]
