Photonics West 2000 sparkles
Last January, the Photonics West 2000 trade show "showcased the power of light" with more than 525 laser, optical, and vision product exhibitors. Of special interest to machine-vision and image-processing attendees were the 106 exhibitors that comprised the Electronic Imaging Pavilion. This specially designated area spotlighted a range of new camera, board, lighting, and software products.
Sponsored by SPIE—The International Society for Optical Engineering; (Bellingham, WA; www.spie.org), the industry event attracted a record attendance of more than 12,140. The large number of exhibitors and attendees contributed to a highly successful event as floor traffic appeared busy for all the three exhibition days, and most of the booths were continually filled with interested professionals.
The Electronic Imaging conference sessions covered 2-D and 3-D displays, image-processing methods, sensors and camera systems, image sequence and data analysis, multimedia processing, optical security, and image and video communications. Other educational opportunities included workshops on the imaging market, advanced imaging technology, and OEM imaging, as well as several short courses in electronic imaging systems.
In the opening standing-room-only plenary session, Carver A. Mead, renowned photonics researcher and scientist at the California Institute of Technology (Berkeley, CA) spoke on the "Evolution in Digital Photography." Mead and his team of researchers are developing a digital color CCD camera for professional studio photographers that produces ultrasharp images with virtually no aliasing, jaggies, or blotches. The on-going 2.5-year camera effort presently involves a standard lens, three prisms and associated electronics, and an attached laptop computer. Striving to achieve a high imaging-system signal-to-noise ratio, the camera system uses 12 million red, green, and blue square pixels and costs approximately $50,000.
On the show floor, new products were not available in great numbers. But of those that were shown, cameras dominated the scene, with a smattering of boards, lamps, and software packages. Among the cameras introduced was the first CMOS-imager-based TL-50 linescan camera product group offered by Dalsa (Waterloo, Ontario, Canada; www.dalsa.com). Providing 2048- to 5150-pixel resolution, the TL-50 transmits Channel Link serialized 8-bit data from the 40-MHz single-channel pixel stream, resulting in line rates to 19 kHz. The company also released the CL-T5 tri-TDI color linescan camera that offers 2048-pixel resolution, 25-MHz per channel scanning through each RGB output, 8-bit digital data at 75-MHz total throughput in LVDS format, and line rates to 10.7 kHz. Dalsa's subsidiary, Silicon Mountain Design, unveiled its SMD-BT25 scientific-grade CCD area-scan camera, which can run at 25 frames/s with 658 x 490-12 bit digital LVDS output.
The Cooke Corp. (Auburn Hills, MI; www.cookecorp. com) introduced its PixelFly digital CCD camera system for demanding scientific, industrial, and machine-vision applications.

Both units measure 44 x 33 x 116 mm, weigh 250 g, and provide shutter ranges from 1/100,000 to 2 s. A one-cable IEEE-1394 connector and link permit multiple cameras to be joined to PCs and compatible devices. The monochrome 1/2-in. interline-transfer CCD XC-ST50 and 1/3-in. interline-transfer CCD XC-ST30 cameras measure 1.8 x 1.2 x 2.3 in. and weigh 3.7 oz.

Market vision
According to a study performed by the Cahners In-Stat Group (Scottsdale, AX), the worldwide semiconductor market will grow by nearly 17% in 2000, with revenues of almost $147 billion. The US market is projected to remain steady. The European region is estimated to climb to 22.3% in 2002. Demand stayed weak in Europe during 1999, and this region continues to lag the United States in Internet infrastructure expansion. The automobile, communications, and Internet sectors should boost European semiconductor sales next year. The explosion of OEMs in Asia/Pacific is figured to increase this region's market share from 22% in 1997 to 29% in 2003. Worldwide semiconductor capital spending is forecast to reach $44.5 billion in 2000 and $60 billion in 2001.
