Graphics imager allows check of designs-in-progress
Combining a laser-writing device with a liquid crystal cell, a California company has developed a graphic imaging system that enables designers to call up computer-generated images directly from their workstations, check the design-in-progress, and resume their work without interrupting the design process.

Determining CRT resolution-(Continued from ID, June 1986)
System resolution performance in today's medical imaging and display equipment is not a simple thing to determine since the sum of the component performances must be considered: the display, the video camera, and the video processing.

Continuous ink-jet produces true color halftone images
Controlling the number of ink drops deposited in each pixel has enabled a group of researchers at Lund Institute of Technology to plot with an ink jet plotter true color halftone images having a variation of color density approaching high quality offset prints.

P-shaped polymer forms ink-jet nozzles in ceramic
In an effort to cut costs of constructing multi-nozzle ink-jet heads and to lower drive voltages, while at the same time producing precision ink passages and ejection nozzles, Japanese researchers used pre-shaped space-forming polymer sheets to create nozzle openings directly in piezoelectric ceramic sandwiches.
