Michael D. WheelerTWINSBURG, Ohio -- The next generation of traffic control systems, employing the latest in video imaging and detection, should be operational in a suburb of Akron by midsummer of next year. Unlike traditional stoplights, this "intelligent transportation system" responds to the changing traffic conditions of an intersection. Sensing backed-up traffic or slower-moving vehicles, a green light stays green longer. Rush hour, once the dread of weary commuters, soon may become manageable as backed-up cars stream through longer green lights. The system was developed by Twinsburg-based Path Master...Read full articleRelated content from Photonics MediaARTICLESQuantum Sensors in Diamond Anvils Measure Materials Under PressureTo develop new, high-performance optical and electronic materials, scientists need to measure how material properties such as magnetism and strength change under extreme conditions.

Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1. At one...Photonics HandbookOptical System Design: Keeping the Coatings in Mind: The design of optical systems should balance the coating constraints with the optical and mechanical requirements. Understanding the key properties and limitations of optical coatings enables the system designer to improve the performance of the optical system.An optical coating engineer is frequently confronted with a difficult specification for a coating. Often the difficulty in the specification results from the particular form of the optical system. If...Photonics HandbookLaser Perforation: The Diffractive Beamsplitter Advantage: Perforated thin sheets of material are required in many applications, including plastic and metal sheets in the packing industry, cartons and metal foil that enable easy tear-off, filters for cigarettes, tubes for liquid or gas drainage, and preweakening of metal sheets for automobile air bags.The basic setup in laser perforation includes a pulsed laser, a lens and either a moving mirror, a rotating web or both.
