Vulcan Hand Scanner
A scanner is a generic term referring to a hand-held sensory device. Scanners were common during the mid-22nd century and used by a variety of space-faring cultures and institutions such as Starfleet, the Earth Sciences Institute, Ferengi privateers, the Suliban Cabal, and the Vulcan High Command.
Scanners were the presumed precursors to the tricorder of the 23rd and 24th centuries.
1950s[edit]
Used by officers in service of the Vulcan High Command as early as 1957, the standard scanner used by Vulcans was a chrome-colored, dome-shaped device with a handle.
The device featured a purple-colored, lighted display screen and could be used to scan for lifesigns. (ENT: "Carbon Creek")
2150s[edit]
Standard scanner
Similar in shape and design as its 21st century counterpart, the scanner used by the Vulcans during the 2150s was also a dome-shaped sensor, with a triangular handle. This device, however, was distinguished by a silver colored readout portion and a blue handle, with black grips. The viewer itself displayed readings in Vulcan script with a generally purple-color glow, the grip featured an array of button controls. (ENT: "Broken Bow")
The Vulcan scanner possessed a maximum scanning radius of three kilometers and performed the same general function as the Earth Starfleet hand scanner. Vulcan sensors, however, were commonly known to be superior during that time. (ENT: "Carpenter Street", "Broken Bow")
Medical scanner
As early as 2153, Vulcans doctors in the service of the High Command were equipped with distinct medical scanners.
Featuring a similarly dome-shaped readout section, this scanner also featured a dome-shaped lower, control portion. It was also distinguished by yellow indicator lights on each side of the display screen.
It was used to scan for certain types of radiation and could, possibly, perform detailed brain scans. (ENT: "The Expanse")
