A vernier scale (/ v ə r ˈ n iː ˈ ə r / ver-NEE-er), named after Pierre Vernier, is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation, thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation ...
A Vernier caliper using the scale invented by Pierre Vernier. Pierre Vernier (French pronunciation: [pjɛʁ vɛʁnje]; 19 August 1580 at Ornans, Franche-Comté (at that time ruled by the Spanish Habsburgs, now part of France) – 14 September 1637, same location) was a French mathematician and instrument inventor.
Vernier acuity (from the term "vernier scale", named after astronomer Pierre Vernier) is a type of visual acuity – more precisely of hyperacuity – that measures the ability to discern a disalignment among two line segments or gratings.
Vernier Software & Technology is an educational software company located in Beaverton, Oregon that produces technology used for scientific education. Vernier is one of the first companies [ 3 ] to popularize the use of computers and sensor technology, known as "probeware" [ 4 ] or "Microcomputer Based Labs" (MBL), during laboratory experiments.
A vernier thruster is a rocket engine used on a spacecraft or launch vehicle for fine adjustments to the attitude or velocity. Depending on the design of a craft's maneuvering and stability systems, it may simply be a smaller thruster complementing the main propulsion system , [ 1 ] or it may complement larger attitude control thrusters, [ 2 ...
Vernier, Switzerland; Vernier (surname) Pierre Vernier, French mathematician and inventor of the Vernier scale; Vernier scale, a secondary measuring device; Vernier thruster, a secondary control mechanism on spacecraft; Vernier throttle, a secondary control mechanism on aircraft; Vernier Software & Technology, an educational technology supplier
Vernier scale (imperial) gives interpolated measurements in fractions of an inch. Retainer : used to block movable part to allow the easy transferring of a measurement. The calipers in the diagram show a primary reading on the metric scale of about 2.475 cm (2.4 cm read from the main scale plus about 0.075 cm from the vernier scale).
Vernier spectroscopy is a type of cavity enhanced laser absorption spectroscopy that is especially sensitive to trace gases. The method uses a frequency comb laser combined with a high finesse [ 1 ] optical cavity to produce an absorption spectrum in a highly parallel manner.
