Uncertainties of measurements on different types of material artifacts range down to 7 X [10.sup.-8] m at 1 m and 8 picometers (pm) at 300 pm.
Piezo stack actuators, for example are short travel devices (<0.2mm travel), providing picometer resolution and high acceleration to 10,000 g's for microsecond responsiveness.
The shear stack provides picometer resolution and good travel ranges.
The CCD optic system with a Paschen-Runge mount assembly delivers a resolution of 8.5 picometer in the wavelength range from 130 to 340 nm.
With nanotechnology becoming a familiar term, scientists are now developing ways to observe and act at the next smaller level: the picometer scale.
In the network, each FBG sensor is called sensor node which is deployed on the critical components of mechanical equipment to monitor the real time temperature (degree) or stress-strain (microstrain/K) that can be calculated by the wavelength shift (picometer, pm).
FEI Company (Nasdaq:FEIC) designs, manufactures and supports a broad range of high-performance microscopy workflow solutions that provide images and answers at the micro-, nano- and picometer scales.
"Pico" is actually the internationally recognized metric prefix for one-trillionth of a unit (10 to the -12th power), as in a "Picometer." A "Nanometer" is one billionth of a meter.
Additionally, Roembke's measuring capabilities are unparalleled in the industry, measuring to the picometer. According to current president, Greg Roembke, "Tight tolerances are required of LSR molding to prevent flash, as LSR will flash in gaps that are less than .0001.
The technique of electron holography allowed Brookhaven scientists to capture images of the electric fields created by the materials' atomic displacement with picometer precision--that's the trillionths-of-a-meter scale crucial to understanding these promising nanoparticles.
