Cameras, motorized lenses, and software debut at Vision 2008
During Vision 2008 (November 4–6, Stuttgart, Germany), numerous vendors introduced products for electronics inspection. MVTec Software announced version 9.0 of its Halcon software. Version 9.0 offers improved speeds via Halcon’s automatic operator parallelization, which distributes processing to the number of available cores. Basler Vision Technologies expanded its product portfolio by announcing the Aviator camera series with two models based on Kodak’s KAI-01050 CCD sensor.
To support applications in which a camera must automatically adjust to different sizes, Leutron Vision has added a motorized-lens option to its PicSight modular cameras. Cameras sporting the option can connect to motorized lenses with C or CS mountings.
By introducing the VCSBC4012 camera, Vision Components extended its VC BoardCam range of intelligent board cameras without a housing. In support of contour-based object recognition, the company highlighted VC Smart Finder software, which allows users to identify structures by means of preset patterns. Also on display was the VC4467 EXview, which features an EXview HAD CCD sensor from Sony that enables the camera to analyze even long wavelength light near the infrared spectrum. The company also announced it has adapted the OpenCV open-source program library to its proprietary VCRT operating system, implementing it on all VC smart cameras.
Dalsa introduced its Spyder3 color camera and two new Genie GigE Vision-compliant cameras—the C1600 and the M1600. Pleora Technologies said that eBUS Driver Suite and PureGEV Suite software are now available for all GigE Vision-compatible products, including cameras not based on the company’s iPORT IP Engines.
Matrox Imaging debuted the Iris GT smart camera and the Solios eV-CL and Solios eM-CL Camera Link frame grabbers. Designed for harsh, environments, the Iris GT is powered by an Intel 1.6-GHz Atom processor and runs Microsoft’s Windows CE 6.0 real-time embedded operating system.
Thermal-imaging system gets upgrade
Used for semiconductor failure analysis, the latest version of the Micro thermal-imaging system from OptoTherm offers a new thermal-imaging camera with a 20-µm/pixel fixed-focus lens, a wide-angle 50° focusable lens, and a 320x240-element uncooled detector. OptoTherm says you can use the Micro system to detect hot spots and shorts, troubleshoot bad components and boards, measure junction temperature, identify die bonding defects, and measure package die thermal resistance.
Micro can measure and display the temperature distribution over the surface of semiconductor devices, enabling quick detection of hot areas that can lead to early failure. The system captures 30 images/s and has a temperature measurement range of 0 to 300°C (32°F to 572°F). Its microscopic lens provides sensitivity of 0.2°C, while the wide-angle lens boasts a sensitivity of 0.05°C. Camera Link and USB interfaces are also provided. www.optotherm.com.
Controllers orchestrate vision systems
Using only two universal control modules, LMI Technologies’ Maestro system simplifies the task of connecting the various components of a machine-vision system. LMI says the system is compatible with all cameras and light sources, as well as all machine-vision-software libraries.
A Maestro configuration comprises the P800 master controller and the C12 camera and light controller. The P800 module interfaces with the encoders and the I/O, delivering microsecond synchronization over CAT5e cables for up to eight cameras and light sources, all from a single power supply. All timing, triggering synchronization, sorting, and reject activations are completed by the P800 module.
Devices are slaves to the P800, including the host computer that performs image processing. Camera image data is delivered directly to the computer over standard interfaces, such as GigE Vision or IEEE 1349, with all timing dictated by the P800 and communicated to the computer over Gigabit Ethernet.
The C12 camera and light controller powers and triggers any camera and also provides synchronized high-current pulses for LEDs or lasers.
You can configure a Maestro system with TCP/IP and XML or with a Web-based browser. You can also integrate LMI’s FireSync, Sensors that See, and Hexsight components with standard camera and lighting components. www.lmitechnologies.com.
