he following pages cover topics related to faster scanning. This is
defined as correctly displaying the ILDA Test Pattern at an angle of 8
degrees or less, at a speed of 50K (50,000 points per second) or more.
The pages listed below provide additional details, and support for these
he TrueK 50 modification to Cambridge
and 6210 scanners allows them to run at ILDA 50K. It provides the same or
better performance than the Cambridge-tuned 6210 scanners.
(Note: The TrueK 50 modification is no longer
being offered by Pangolin.)
ambridge Technology Inc. introduced faster scanning in spring 1999,
with the model 6210 scanner and faster-tuned scanner amps.

standard of comparison, and how to determine scan angles.
ive different scanning systems compared in over 50 photographs. The
photos are in two general categories: test patterns and sample frames from
Lightspeed's "Creation" show.
Test pattern photos. Comparing
the ILDA Test Pattern at its largest compliant size, at about 30
degrees, and a square wave test pattern.
Creation photos. Comparing
rounding of square corners, an abstract frame, and a raster frame.
