This week Point Grey Research unveils the Dragonfly Express, its first IEEE1394b camera product at The Vision Show East in Boston.
This week Point Grey Research unveils the Dragonfly Express, its first IEEE1394b camera product at The Vision Show East in Boston.
As an extension of the very popular Dragonfly camera, this high-speed version uses the new IEEE1394b interface and the Kodak KAI-0340M VGA charge-coupled-device (CCD) sensor to stream 640 x 480 images at greater than 175 frames per second.
Maintaining most features of the original Dragonfly camera, the Express is ideal for OEM integrations.
Via the new 1394b interface, users can take advantage of up to 80Mbyte/s of data transfer doubling the bandwidth available with 1394a.
Point Grey was able to fast-track the development of its 1394b camera by designing its own 1394b link layer in a Xilinx FPGA as opposed to sourcing the components from a semiconductor vendor.
"By continually providing customers with innovative products we stay ahead of the game", comments Vlad Tucakov, Director at Point Grey.
The Dragonfly Express incorporates the Kodak KAI-0340M image sensor, a 640 x 480 resolution, one-third-inch optical format, progressive scan interline transfer CCD.
The KAI-0340M has additional features of electronic shuttering, peak QE (quantum efficiency) of 55%, extremely low noise and low dark current.
These features give the KAI-0340M exceptional sensitivity.
"We are pleased to work with Point Grey Research on this exciting new product.
I believe this camera will provide customers a new level of performance that is especially needed in many industrial applications", states Terry Guy, Product Marketing Manager at Eastman Kodak Company, Image Sensor Solutions.
