Adaptive Algorithms, Multi-Cores, and Networks Mark New Machine Vision Era

Potato chips, cell phones, razors, and baby diapers are just a few of the many everyday items made with the help of industrial machine vision. In fact, any product that is manufactured in either high volume, high accuracy, low cost, or a combination of all three can be made better, faster, and less expensively using machine vision.

Infrared Vision: SWIR Sees the Furnace Through the Flames

The ability to make thermal measurements and image through materials that confound more expensive thermal cameras is pushing shortwave infrared (SWIR) sensors into a growing number of industrial process monitoring and thermography applications, typically those of 100 °C or more.

Medical Imaging: Multimodal Techniques Find Life’s Answers

Traditional research on disease mechanisms in animal models mainly has relied either on the detection of morphological changes of the diseased tissues obtained through anatomical imaging, or on the excision and pathological study of the tissues of interest. These methods often require long time periods for measurable changes to occur and large numbers of test animals because multiple animals are often sacrificed at each experimental point for histological testing.

Middleware Bridges the Optical/Mechanical Design Gap

Mechanical CAD (computer-aided design) programs have become very sophisticated during the past few years. Unfortunately, there is still a portion of the engineering spectrum that cannot be handled well in a traditional CAD program: optical modeling. If you are creating a complicated optical system (think of a camera zoom lens), then it is best to perform almost all of the design in a specialized optical design software program and then transfer the optical design to a CAD program for the later stages of the design process where items like housings, threads, cams, and motors are designed and integrated into the model.

The Air Bearing Advantage in High-Precision Positioning

All moving objects possess six degrees of freedom — three linear and three rotary. The task of a linear motion guideway is to eliminate, as closely as possible, five of these degrees of freedom, leaving a single rotary or linear axis of motion. Air bearings are the purest and highest-performance means of defining linear or rotary motion, and have substantial advantages over conventional mechanical guideways. These advantages become more pronounced as the desired resolution increases, and many aspects of high-precision positioning are uniquely enhanced when air bearing guideways are chosen.

DPSS Micromachining Puts Shine on Industrial Molds

Modular diode-pumped solid state (DPSS) lasers make it easy to tailor laser sources to micromachining applications, such as steel and ceramic molds. Lasers are now used to micromachine virtually every type of material, including metals, plastics, glass, and ceramics. Micromachining is a highly diverse market that uses flash-pumped, diode-pumped solid-state (DPSS), and excimer lasers. Excimer lasers provide more average power at shorter wavelengths, enabling more precise micromachining, but as DPSS lasers have added increased average output power to their lower acquisition and operation costs, small footprint, improved mode operation, and high-repetition pulse rate, DPSS systems are grabbing a larger share of the micromachining market.
