Imperx (Boca Raton, FL) has introduced high-performance cameras utilizing the CoaXPress interface standard. The ICX camera family provides resolutions ranging from VGA to 29 megapixels, and the devices capture images at up to 260 frames per second (fps).The CoaXPress interface provides high-speed, point-to-point serial communications for transmitting still images or video from a camera to a host system, typically a frame grabber. In addition, it provides a 20 Mbps uplink for communications and control from host to camera. The interface also offers triggering capability, fixed low latency, and up to 13W of 24-volt power to the camera. The protocol supports plug-and-play operation, using a Gen<i>Cam compliant XML file inside the camera to expose a camera's features to the host.
The ICX cameras operate the CoaXPress interface at 2.5 Gbps, which allows cable lengths to be greater than 100m between camera and frame-grabber. ICX models range from 648 × 488 pixels (VGA), using a 1/3-inch sensor operating at 260 fps, to 6600 × 4400 pixels, using a 35mm sensor operating at 2.5 fps.
