e2v's industrial inspection cameras offer significant benefits
:: 14 November, 2007
e2v is launching the Eliixa range of industrial inspection cameras. The Eliixa multilinear camera is a true 4k pixel (4096 pixels) camera with several advanced features - such as row spacing of only two pixels (centre to centre), a line rate of 18kHz, enhanced blue response, and three lines (RGB) or four lines (RGB plus a fourth line either monochrome or near-infrared).
According to the company, the Eliixa camera provides a significant advantage when compared to other colour cameras currently on the market.
The arrangement of one 4k pixel line per colour with smart management of space correction yields a true resolution of 4k and a high modulation transfer function (MTF) that is claimed to be higher than single- or dual-line cameras utilising interpolation techniques. When compared to trilinear cameras, the Eliixa is said to be the only camera with a high speed of 18,000 lines per second coupled with a minimal row spacing of 10 microns.
This allows it to be more flexibly positioned in the system at angles that can be slightly away from 90degrees to the object. Blue response is also boosted due to e2v's image sensor back-thinning process technology, providing users with a wider choice of lighting options.
The Eliixa trilinear version (RGB) is said to be good alternative to expensive prism-based cameras and their costly specific optics. In quadrilinear format, the Eliixa provides for an all-in-one approach, with a single Eliixa camera capable of replacing a two-camera system consisting of a conventional colour camera and a monochrome or near infrared (NIR) camera.
Christophe Robinet, strategic marketing manager for industrial imaging products at e2v, comments: “The camera has been designed to increase system efficiency and save cost at vision system level. The Eliixa camera offers easy calibration (test pattern, flat field correction, white balance, excellent mechanical alignment), versatile implementation (trigger modes, output modes, bidirectional scanning, spatial correction), optimal mechanical design (70mm width) using e2v's unique imaging technology, especially at sensor level. The Eliixa camera breaks new ground in multi-wavelength detection systems, including NIR, with functionality that enables our customers to get the best out of a great product.”
The Eliixa camera is suitable for web inspection (such as printing or currency), surface inspection (printed circuit board, wood, tiles, etc), scanning (high-end document processing, film scanning, postal sorting, etc) and inspections within food, pharmaceutical, medical and packaging systems. The embedded NIR channel is of particular interest for the food sorting and the film/document scanning segments.
Eliixa cameras will be available in three versions (one trilinear and two quadrilinear), and each will be offered in full pixel rate (320MHz) and half pixel rate (160MHz). Initial prototype units will be available at the end of 2007, with the first production units scheduled for delivery in March 2008.
