TRICORDER

In the fictional Star Trek universe, a 'tricorder' is a handheld device used for scanning an area, interpreting and displaying data from scans to the user, and recording information to isolinear chips.
Three primary variants of the tricorder are issued by Starfleet. The standard tricorder is a general-purpose device used primarily to scout unfamiliar areas. The medical tricorder is used by doctors to help diagnose diseases and collect bodily information about a patient; the key difference between this and a standard tricorder is a detachable hand-held high-resolution sensor array stored in a compartment on the front of the tricorder when not in use, making it slightly bigger than a standard tricorder. The engineering tricorder is fine-tuned for starship engineering purposes. There are also many other lesser-used varieties of special use tricorders.
According to Dr. Julian Bashir, while medical tricorders are very good at scanning living people, they are not very good at scanning dead ones. Evidently this is the first lesson taught at Starfleet medical school.
The tricorder of the 23rd century was a heavy, black, rectangular device with a small screen and a shoulder strap. The 24th century unit is a small, gray, square model with a flip-out panel to allow for a larger screen. This design was further refined later on with a slightly more angular appearance that was seen on most of the TNG-era movies as well as later seasons of and . The medical variants of this model had the detachable scanner stored in the bottom of it when not in use as opposed to the front, giving this model the same overall profile regardless of its intended use. Later in the post next generation era, and , a newer tricorder is introduced. It is flatter, and looks more like a palm pilot, with a small flap that flips up on the top and a large touch screen interface.

The tricorder prop for the was designed and built by Wah Ming Chang, one of several futuristic props he created under his contract. Some of his designs are considered to have been influential on later, real-world consumer electronics devices. (See also: Martin Cooper and the Star Trek communicator.)

"Real" tricorders

Software exists to make hand-held devices simulate a tricorder. Examples include Jeff Jetton's Tricorder - 2.0 for the PalmPilot and the "genuine Tricorder from Elegant Solutions" for the Pocket PC. There is considerable interest in developing real portable analysers which could behave like a tricorder.
Vital Technologies Corporation sold a portable device dubbed the "Official Star-Trek Tricorder Mark 1" (formally, the TR-107 Tricorder Mark 1) in 1996. Its features were an "Electromagnetic Field (EMF) Meter(R)", "Two-Mode Weather Station(R)", (thermometer and barometer), "Colorimeter(R)" (no wavelength given), "Light Meter"(R), and "Stardate Clock and Timer(R)" (a clock and timer). Spokespersons claimed the device was a "serious scientific instrument".[1] Vital Technologies sold 10,000 units before going out of business. The company was permitted to call this device a "tricorder" because Gene Roddenberry's contract included a clause allowing any company able to create functioning technology to use the name.
In February, 2007, researchers from Purdue University publicly announced their portable (briefcase-sized) DESI-based mass spectrometer, the ''Mini-10''[2], which can be used to analyze compounds in ambient conditions without prior sample preparation. This was also announced as a "tricorder".[3]
Sandia National Labs in the US is a major centre for lab-on-a-chip research, and have developed many handheld instruments for biological or chemical analysis.[4]
