This year, Vision Systems Designcelebrates its 20th anniversary. Throughout the year—as part of our Vision 20/20 series— we are going to encourage people to think about where the imaging and machine vision industry could be headed in the next20 years, while also taking a look back at the past 20 years.
As we usher in the new era of John Lewis as our Editor in Chief, I thought it would be fun to once again take a look back to the very first year that Vision Systems Design was published. In the December editorial, Andy’s article “Machine vision – more than a pass/fail decision,” provided some information on a phone call Andy received in regards to a systems integration problem.
The problem, explained the reader, involved parts not being placed in the correct location on the machine, and the issues that arise with having to shut down the machine and clean it up. Andy went on to provide more details on the problem, as well as propose a solution that involved more than just a “simple pass/fail system.”
In the lead feature article of the issue, a system that uses multispectral imaging to assess meat is described. At the Instituto Nazionale di Ottica (Florence, Italy), a system capable of inspecting meat carcasses was developed that used a combination of visible, x-ray, and IR detectors and sensors. In operation, images of hanging meat samples are taken at 120° from each other, which allows a complete 360° view of the meat carcasses to be obtained.
For detection of defects not seen under visible light, IR detectors in the 3-5-µm range visualize internal subcutaneous blisters. For internal inspection, x-ray sources and detectors are used. Learn more about this system here.
Elsewhere in the issue, Andy wrote about smart weapons in the Gulf War, medical imaging, image processing demands, robotic surgery, color edge detection, and how Pixar once designed a system specifically designed to render 3D images.
In this issue’s new products section, Andy covered—among a number of other new products—a color TDI camera, a three-axis measurement system, a laser measurement system, a dual DSP board, and a CCD camera.
Take a look at the December 1996 issue.
We will continue to highlight archived issues in the future, so keep an eye out for more “blast from the past” articles from Vision Systems Design.
