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.

scanning head. 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 [7], 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 systems.
Laser Design has added an automated Renishaw PH 10
scanning head to its Surveyor 3-D laser metrology systems.
