Features

Fixed-Mount Reader

Cognex Corp., Natick, MA, offers the DataMan 200 image-based ID reader that features real-time data and image transfer, and integration with plant controllers and information networks. Liquid lens technology, an optional feature, provides greater focal range and fast setup time. The technology adjusts the camera’s focus by applying an electrical charge to fluid within the lens. Autofocus can be achieved with a single software command. The lens also includes no moving parts and is resistant to shock, vibration, and wear. Setup is performed using two laser aimers.

Camera System

SICK, Minneapolis, MN, offers the ICR890-2000 CCD-based camera system that reads 1D and 2D bar codes, and includes an integrated real-time JPEG encoder that allows high-quality images to take up less storage space. It also includes increased processing power, support of multiple image output paths, optimized decoders, and extended XML file content. The illumination is fully integrated and the output is self-monitored to provide even lighting over a range of reading situations without adjustment.

Display Panels

Z Microsystems, San Diego, CA, offers the Ground Control Station display panels with real-time enhanced video. The LCD panels use an FPGA to execute image enhancement algorithms in real time for live video surveillance feeds. The display applies image enhancement and edge detection algorithms to incoming video streams without adding latency. The edge detection algorithm identifies analogous shapes and highlights details. The displays brighten or darken for dusk and dawn viewing, de-haze images, and are qualified to MIL-SPECs for shock, vibration, EMI, temperature, and humidity.

Industrial PCs Offer Configurable System Options and Quad-Core Performance

Industrial PCs (IPCs) are all about performance, including processors, mass storage performance, and network throughput. In all applications — medical, communications, automation, process control, transportation, military and defense, and more — bandwidth requirements for data transmission and processing are on the rise. Long-term use, low-level noise tolerance, ruggedness for shock and vibration, extended availability of additional systems — these are just some of the top-level requirements that must be considered in pairing the right industrial solution to the right application.

Choosing the Right Camera for Thermography Projects

Infrared (IR) thermography is an indispensable tool for studying dynamic thermal phenomena. This type of imaging is accomplished with an IR camera (Figure 1) that converts infrared radiation into a visual image depicting temperature variations across an object or scene. In addition, a good IR camera makes accurate (±1°C to ±2°C) non-contact measurements of the object’s temperatures.

Comparing Emissivity Evaluation Methods for Infrared Sources

Heat transfer is governed by three distinct mechanisms: convection, conduction, and radiation. Unlike convection or conduction, heat transfer through radiation does not occur through a particular medium. To understand this phenomenon one must enter into the atomic or quantum realm. All atoms, at finite temperatures, are continuously in motion. Consequently, it may be understood that the mechanism of radiation is derived from the energetic vibrations and oscillations of these atomic particles, namely electrons.
