The scanning head
produces a laser stripe that consists of approximately 1,000 measured points.
SPGPrints' digital printing machine offerings include its high productivity, fixed-array PIKE(r) printer, capable of printing up to 13 million linear metres per year, and its scanning head
JAVELIN(r) printer for outputting up to 2 million linear metres annually.

. Four outer electrodes of outer PT (Z-PT) are electrically connected as a single intact electrode.
Achieving this target price placed huge constraints on the component costs, resulting in a design philosophy to use the minimum possible hardware in the scanning head
and to connect to any available pC via USB, to perform signal/image processing and display.
During this control phase, angles [[??].sub.Z], [[psi].sub.z] determine the set (desired) motion which should be made by the axis of the scanning head
Although the performance of the laser Doppler vibrometry is improved in terms of scan angles and automatic focusing , it has still disadvantage that retroreflective film should be attached on target surfaces to improve signal-to-noise ratio when a scanning head
is located far from the target [8-10].
With a flat design, no integral bearing, and a small scanning head
, HEIDENHAIN's (Schaumburg, IL) new ERO 6000 angle encoder is applicable in metrology systems, compact rotary tables, and high-dynamic applications.
Measurement sensors are mounted on the sides of the scanning head
to avoid the risk of dust or grease falling onto the web.
A galvo scanning head
and servo positioning axes can be fitted to enable the Cube to process large parts or large trays of smaller parts.
SunJet has supported the industry developments in LED UV lamp technology for several years, and was one of the first ink companies to recognize the potential benefits to customers of inks which have the ability to part cure or "pin" with UV LED lamp exposure in scanning head
Laser Design has added an automated Renishaw PH 10 scanning head
to its Surveyor 3-D laser metrology systems.
