Optronis high speed 4 Megapixel, 500fps camera using CoaXPress CXP-6, BNC 4x real-time interface at 25Gb/s transfer rate Dr Bernd Reinke Optronis


The CL4000CXP from Optronis is the first 4 Megapixel camera with a CoaXPress interface, which


enables real-time transmission of 500 images per second. It boasts pixel rates of 2GB/s, which corresponds to a net data rate of 16Gb/s with serial transmission and 8 bits per pixel.


A distinguishing feature of the interface is the serial transmission concept. Data is transferred at gross clock speeds of up to 6.25Gb/s through a 75 ohm coaxial cable. The solution can also be scaled up by using several cables at once. Scalability represents a key benefit, as it allows enhanced performance by using several serial transmission channels in parallel. With a cable length of up to 130 metres, the Optronis CoaXPress camera also has a flexible range of potential applications. www.optronis.com


World’s fastest camera and its utility to scientific, industrial, and biomedical applications Keisuke Goda Photonics Laboratory at UCLA, Department of Electrical Engineering, University of California


The team at University of California, Los Angeles (UCLA) has developed an entirely new type of imager that offers 1,000 times higher frame rates and shutter speeds than conventional CCD and CMOS cameras. This camera, known as serial time-encoded amplified imaging or microscopy (STEAM), builds on fibre-optic communication technology, in particular optical signal processing methods.


In STEAM, the image of an object is encoded into a serial time-domain waveform, which is then optically amplified and captured, not by a detector array, but instead by a single-pixel photodiode. The main attributes of the STEAM camera are firstly the optical image amplification and serialisation and secondly the elimination of the detector array – when combined, they enable


continuous real-time operation at a frame rate of more than 10MHz and a shutter speed of less than 500ps. STEAM’s optical image amplifier


circumvents the fundamental trade-off between sensitivity and speed. The STEAM camera operates continuously and can capture dynamics of ultrafast transient events without any knowledge of the timing of their occurrence. www.photonics.ucla.edu


Pleora eBUS SDK 2.1 with eBUS Universal Pro driver allows vision industry to leverage 10 GigE using off-the-shelf computer hardware John Phillips Pleora Technologies


Improvements in sensor design, yielding steady increases in resolution and frame rates, have now accelerated the demand for high-speed


camera interfaces. Although first introduced more than eight years ago, sales of 10 GigE switches and network interface cards (NICs) are only now ramping up in mainstream markets – including the machine vision market. To facilitate the adoption of 10 GigE in machine vision markets, Pleora has released an updated version of its eBUS SDK, which is a toolkit for the development of high- performance applications that use the GigE Vision standard. The SDK includes the eBUS Universal Pro driver, featuring an entirely new architecture designed to accommodate the increased bandwidth afforded by 10 GigE solutions. This innovation allows vision system designers to use commercially available NICs and cost-effective multicore PCs, while developing applications that can receive and process video over 10 GigE interfaces at rates of more than 8Gb/s. www.pleora.com


Automatic Test Equipment (ATE) for optical measurement of saw blades Bernd Moser


ProOpt-Systemtechnik


ProOpt-Systemtechnik (Etzbach, Germany) has developed a product line of optical, automatic test equipment (ATE) for


quality assurance and production optimisation. Developed specifically for circular devices and saw blades, the integrated sawBlade Light system performs an optical measurement of a saw blade and cut tooth geometry. Two independent cameras capture images of the saw: the vertical camera measures the thickness and the radial and axial run-out of the individual cut tooth, while the side camera is used for measuring the tooth geometry (cutting angle, spatial tooth, etc) and monitoring individual measuring positions. All measurement results are saved in a built-in database. The system recognises when components are faulty and information on the product and production equipment can be stored in the integrated electronic expert system. www.proopt.eu


GigE PowerPlus camera series with freely programmable FPGA Markus Hold Videor E. Hartig


The Japanese camera manufacturer, Sensor Technologies (Sentech), now offers a series of GigE cameras with two FPGA modules. The cameras are supplied by Videor. One of the FPGAs is fully accessible to users, featuring open programmability for application-specific image processing.


The Sentech camera family uses an XC3SD1800A model Xilinx Spartan-3 FPGA with 8Mb ROM for configuration. The ‘User FPGA’ is unused on delivery and fully accessible. Furthermore, there is a 32MB DDR 2 memory usable for storing image data. The image data is created by a CCD


sensor, then digitised in the A/D converter and transmitted to the Sentech FPGA for all processing of white balance, gamma correction, and colour interpolation. This FPGA also controls the parameters of video such as shutter, gain, and aperture. If the ‘User FPGA’ is active, the FPGA programmer now has the option of uncoupling the image data at different positions for real-time processing.


Image comparisons and analyses can be made in the ‘User FPGA’ in addition to pure frame manipulations, such as noise suppression, colour space conversion as well as colour and image manipulations. The results of the pre-processing, for example a good/bad decision, can be output over a total of five optically-coupled I/Os. Three
