The tricorder is the standard hand held sensor data communications devise in use by Star Fleet. The tricorder incorporates miniaturized versions of the senors most often used by crew members either on a ship or station or on away mission. The abilities of the tricorder may be augmented by the use of peripheral scanners or other such equipment.

There are three two types of tricorders in use in the fleet the standard tricorder and the medial tricorder, where the medical tricorder is equipped with a peripheral hand scanner with miniaturized medical sensors.

Standard Tricorder:

The tricorder currently used by Star Fleet measures 15.81 by 7.62 by 2.84 centimeters with a weight of 298.3 grams. The casing is gamma-strengthened polyduranide. Power is provided by an induction-rechargeable sarium-krellide energy cell rated for thirty-six hours of continuous use.

The sensor systems of the tricorder consist of 315 mechanical, EM, and subspace devices mounted around the internal frame and embedded in the casing. 189 are clustered in the forward end for directional readings with a field of view lower limit of 52.3 arc- seconds. The other 126 omnidirectional devices make measurements of the surroundings pace.

The primary computing segments are divided among the inner casing surfaces and is rated at 275 giga-floating point calculations per second. Data storage is provided by eight wafers of densified chromopolymer isolinear crystal for a total capacity of 9.12 kiloquads.

The control and display interface routes commands from the panel buttons and display screen to the PMCS for execution for tricorder functions. The Opaque control surfaces area fabricated from thin-film copper dilefinate infused with metallic dyes to fix the graphical content. Below is a list of the buttons on the control surfaces of the tricorder along with a description of the buttons function.



If the tricorder is not used for ten minutes the power standby indicator light will illuminate and the tricorder goes into low-power mode. Touching any control will bring the devise back to full power. If the tricorder is stowed but performing ongoing tasks the tricorder will not go into low-power mode until the tasks are completed.


Control function select switch. This is a convenient toggle for often repeated function changes and may be preprogramed by the individual crew member.

I and E:

These two controls managed the source of sensory information. Either the tricorder itself (internal) or remote device (external), or both sources at the same time. The remote device can be any sensor platform that sues the same data collection machine language. The term platform denotes any vehicle operating on or above another a planetary body, such as a ship.


This screen is capable of showing any real time, stored, or computed image. The display area is similar in construction and function to Star Fleet control panels and display screens. Although the layering technique is simplified and the default image size is naturally smaller. Selected areas of the image may be enlarged by touch; many other screen functions may be customized using the standard tricorder’s stored setup program.


The standard tricorder contains a read/write drive to record information onto small crystal memory chips for later retrieval, or to load previously recorded information into the tricorder’s main memory. Each chip has a maximum capacity of 4.5 kiloquads.


These indicators denote which data recordings or retrieval activity is taking place in the tricorder library section. A more detailed readout of data operations can be called up on the display screen.


Each of these three key can be assigned to manage up to nine remote devices, for a total of twenty-seven different information sources. For a routine away mission, the default settings on power-up are GEO, MET, and BIO, covering geological, meteorological, and biological functions.


This section controls the transmission of data and images to and from the tricorder through the STA. ACCEPT toggles the tricorder to accept one-way transmissions form a designated remote source. POOL: Allows for networking of the tricorder and one or more designated remote sources.


Sets up a special tricorder to ship data link employing multiple high capacity channels.


Sets up a similar high capacity link, but to other tricorders. While all four modes can be active simultaneously, the system will slow down significantly. In practice, no more than two modes are usually necessary at one time.


This is the emergency “dump everything to the ship” button. It provides for non-error-checking burst mode data transmission in critical situations. In practice this function can be used no more than two times before the standard tricorder’s primary power is exhausted. All sensing tasks are suspended and power is maximized to the STA .


This section manages single or sequential image files recorded by the tricorder. The control has for divisions: FORWARD, REVERSE, INPUT, and ERASE. When used in concert with other tricorder functions, relatively complete documentation of an away mission can be achieved. At standard imaging resolution at a normal recording speed of 120 Area View Changes (AVC)/Sec. The tricorder can store a total of 4.5 hours of sequential images. Higher speeds yield a proportionately lower total recording time.


Library B is the primary storage area for sequential images, though the memory configuration may be changed to include other storage areas, depending on the application. I and E control the image source.


This touch pad may be used to personalize a tricorder for default power-up settings, or as a security device for single crew member operations.

Medical Tricorder:

The medical tricorder consists of a standard tricorder to which is added a specialized medical peripheral device. The MP comprises two components, the computing section and deployable high-resolution sensor. The MP measures 8.5 by 3.0 by 3.0 cm and masses 430 grams. The function controls of the standard tricorder may be used to configure custom scan modes for the case-mounted and hand sensors with menu choices visible on the main display screen.

When not in use, the MP is housed in a docking block that is attached to the upper edge of the tricorder. The docking block housed an auxiliary sarium krellied power cell, sensor assemblies and peripheral processing and memory storage.

The peripheral housing block contains 86 electromagnetic devices mounted about the internal frame, upper and side panels of the casing and the forward section of the hand sensor receptacle. None to the sensors are omnidirectional but specialized for medical readings and contains a field of view of limits of one fourth of a degree. The hand sensor incorporated fifteen high-resolution devices for readings down to thirty seconds of an arc.
