- Tricorder
In the fictional
Star Trek universe , a tricorder is a handheld device used for scanning an area, interpreting and displayingdata from scans to the user, and recording information.Three primary variants of the tricorder were issued in
Star Trek 'sStarfleet . 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. Theengineering tricorder is fine-tuned forstarship engineering purposes. There are also many other lesser-used varieties of special use tricorders.According to Dr.
Julian Bashir (from ""), 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.Different types of tricorders
The tricorder of the 23rd century was a heavy, black, rectangular device with a small screen and a shoulder strap. 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. 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 '.
In the post-"Next Generation" era ("
Star Trek Nemesis " and ""), a newer tricorder was introduced. It is flatter, and looks more like a modern-dayPDA with a small flap that opens on top and a largetouch screen interface.List of tricorders

** Slim,PADD -like tricorder, with touch-screen interfaceThe 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.Who|date=December 2007 (See also:

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 thePocket PC , iPhone, and iPod TouchWeb application . 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", "Two-Mode Weather Station", (thermometer andbarometer ), "Colorimeter " (no wavelength given), "Light Meter ", and "Stardate Clock and Timer" (a clock and timer). Spokespersons claimed the device was a "serious scientific instrument". [ [http://www.stim.com/Stim-x/0996September/Sparky/tricorder.html Real Tricorders] ] Vital Technologies sold 10,000 units before going out of business. The company was permitted to call this device a "tricorder" becauseGene 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-basedmass spectrometer , the "Mini-10", [ [http://www.purdue.edu/UNS/html4ever/2006/060316.Cooks.desi06.html Purdue chemical-analysis method promises fast results ] ] which can be used to analyze compounds in ambient conditions without prior sample preparation. This was also announced as a "tricorder".

The day after the announcement, technology websites including Inside Tech [ [http://www.dailytech.com/article.aspx?newsid=12322 "New 'miracle diagnosis' handheld medical scanner 800 times more sensitive than full-size scanners"] , "DailyTech ", July 10, 2008] and The Future of Things [ [http://www.tfot.info/news/1202/science-fiction-saving-lives.html Science Fiction Saving Lives - TFOT ] ] began comparing this device to the Star Trek tricorder.See also
