TECH FOCUS: COAXPRESS Optronis Featured product


Commercial products


Along with products from the likes of Euresys, Basler, BitFlow and Optronis (see the featured products) – Euresys has also introduced a Coaxpress-over- fibre bridge IP core – new on the market are frame grabbers from Matrox Imaging and cameras from Adimec and SVS- Vistek. Te Matrox Rapixo CXP Quad


65MPixel camera with fast 50Gbps image data transmission


Industrial inspection often requires high resolution combined with high frame rate. Interface technology has to deal with the resulting requirement of high bandwidth. CoaXPress interface version 2.0 and version 2.1 revised 2021 allows 12.5Gbps per channel. More demanding machine vision applications can be addressed by combining four channels to transmit at 50Gbps. The Cyclone-65-70


camera with CoaXPress 2.0 interface integrates a large 65 MPixel image sensor with 9,344 x 7,000

if electrical isolation is required between the camera and the PC. Additionally, as speeds


increase further, such as 25Gb/s operation per cable, it’s inevitable that optical will win over copper. Terefore, it’s very important that Coaxpress has fibre support, so it can leverage the investment going into high- speed fibre for Ethernet, while simultaneously maintaining the proven real-time Coaxpress protocol. Both the addition of GenDC


pixel. Full resolution images are transmitted at up to 71fps. Reduced resolution images are possible to increase frame rate beyond 12,000fps. The sensor has high light sensitivity, excellent image quality and low noise. Small camera housing with different lens mounts open applications in factory automation and quality assurance. Flexible cooling options, either with active and passive colling, are available to deal with harsh environments.

and the fibre protocol are still very new, so it’s a bit early to say much about products. In terms of GenDC, it’s probable that 3D cameras will be the first to take advantage of this. Te higher speeds of CXP v2 have already allowed equipment providers to upgrade their products to use faster sensors. GenDC clearly allows the 3D camera vendors to make much faster cameras than the typical gigabit Ethernet products currently on the market. So, watch this space!


28 IMAGING AND MACHINE VISION EUROPE APRIL/MAY 2021


Data Forwarding, the latest in the Matrox Rapixo CXP series of frame grabbers, combines Coaxpress 2.0 connectivity with a data-forwarding option to distribute image processing across multiple computers. Available for either CXP-6 or CXP-12, these boards minimise system latency, re-transmitting all image data prior to storing it in the onboard memory. Te Matrox Rapixo CXP


series also includes single, dual and quad boards without data forwarding capabilities. Te whole series pairs readily with Matrox Imaging vision software which, following updates early this year, will include two new utilities: Matrox Capture Works, a configuration and test tool for GenICam-based interface standards, simplifying the setup and configuration of Coaxpress cameras; and Matrox Gecho, a command-line tool used for probing video capture with a small memory footprint. Matrox Gecho logs numerous


acquisition-related events for post-analysis of performance issues if these occur. Active Silicon’s 4xCXP-12


FireBird range of acquisition cards also supports Coaxpress 2.0. Based on a Gen3 PCI Express interface, the frame grabber uses the ActiveDMA Risc-based engine to give zero CPU intervention, providing high-speed and low-latency image data transfers. New from Adimec is


the high-speed Quartz Q-21A230 for electronics and semiconductor inspection, and the Diamond D-65A30-T and D-65A09 developed for display inspection, all Coaxpress cameras. Te Quartz Q-21A230


is designed for real-time metrology tasks. It uses a Gpixel Gsprint 4521 21-megapixel global shutter sensor, with a 4.5µm pixel and 230fps. Te camera operates in different performance modes, including maximum dynamic range, high full well and maximum sensitivity. Te Diamond D-65A30-T is optimised for ultra high resolution in-line OLED, LED and MicroLED display module inspection. It uses the Gpixel Gmax3265 sensor, offering 9,344 x 7,000-pixel resolution with 3.2µm pixels. For de-Mura and display pixel
