July 19, 2022 - Aggressively positioning itself for leadership in the machine vision industry, SVS-Vistek, a world-class provider of imaging technology, has launched the shr661, the highest resolution commercially available camera to feature a global shutter. Even on high-speed conveyor belts, the 127-megapixel CMOS global shutter sensor ensures distortion-free inspection of complex objects including solar panels, flat panel displays, printed circuit boards, and semiconductor wafers, among others. The new camera is available with either the powerful CoaXPress-12 interface that transmits 17 frames-per-second (fps) at full resolution (13392 x 9528 pixels), or a 10GigE interface model for up to 6.5 fps.
Global shutter eliminates motion blur
Based on the next generation Sony Pregius sensor IMX661 sensor with a pixel size of 3.45 µm, the shr661 camera achieves superior stopping power of fast moving objects, avoiding motion blur and artifacts since its full pixel array is exposed simultaneously by the global shutter, rather than line-by-line.
Other cameras in the ultra-high resolution range rely on rolling shutter sensors that experience spatial distortion of moving objects, known as the "rolling shutter effect," since the sensor must read each line of the array sequentially. The larger the sensor, the longer rolling shutter readout takes, and the worse the blurring. Also, synchronizing a rolling shutter camera to other components, such as a light source, is difficult due to the time delay between the lines of the sensor. The end result is slower cycle times and fewer frames-per-second relative to those achievable in global shutter.
Owing to its global shutter, the shr661 stands alone in its ability to simultaneously deliver on many key performance parameters, overcoming the compromises that are inherent to current ultra-high resolution cameras, and eliminating the drawbacks associated with rolling shutter sensors.
Excellent image quality
Heat is always an issue with larger sensors. SVS-Vistek’s proven, highly advanced thermal management system ensures stable temperature distribution on the sensor and therefore, consistent image homogeneity with outstanding dynamic range. Flat Field Correction and Defect Pixel Correction can be adjusted by the user to meet their respective lighting and application requirements. Multiple inputs and four power-out outputs support precise triggering as well as sequencers and logical operators. The camera can be operated with 8, 10 or 14 bit color depth for further versatility.
SVS-Vistek shr661 cameras are GenICam complaint with the GenTL interface to enable easier integration into all major machine vision software packages.
