Industrial imaging applications often face challenges related to motion artifacts, particularly when using rolling shutters. These shutters are easier to produce but can distort images of moving objects—a limitation that new cameras from SVS-Vistek aim to solve.

Gpixel Sensors: A High-Performance Foundation

The HR camera series (hr49, hr51, hr65) leverages advanced Gpixel GMAX sensors as an alternative to traditional CMOS and CCD technology. These sensors incorporate a global shutter feature essential for capturing motion without distortion. Additionally, SVS-Vistek has introduced a novel image optimization process for the CMOS sensor used in these cameras.

This optimization addresses variations in sensitivity gradients during manufacturing—a common issue with stitched sensors like the hr51 model from Gpixel. By compensating for differences in optical paths, this correction ensures excellent homogeneity and detail across images captured by entocentric or telecentric lenses while also mitigating fixed pattern noise (FPN) and bad pixels.

Model Evolution: Replacing Legacy Systems

The KAI29050 sensor from ON Semiconductor was once popular for 4:3 aspect ratio applications. However, the new hr51 model with a pixel size of 4.6 µm offers higher resolution (8424 x 6032 pixels) and faster frame rates (up to 30 fps), making it an ideal replacement.

For square sensor requirements, the hr49 model provides approximately 7000 x 7000 pixels at a speed of 17 fps. This camera is compatible with numerous lenses available on the market today. The hr25 model also offers a similar aspect ratio but in APS-C format—ideal for applications requiring up to 25 megapixels.

The largest resolution among these models comes from the hr65, which features 9344 x 7000 pixels and is currently one of the most affordable 65-megapixel cameras with a global shutter. Like other HR cameras in this lineup, it boasts an impressive frame rate of up to 17 fps.

Fast Imaging for Motion Analysis

These high-resolution cameras are ideal for applications involving moving objects where distortion-free imaging is critical. The modern interfaces (Camera Link 80-bit, CoaXpress) ensure flexible integration into various systems while maintaining optimal performance.

The hr49, hr51, and hr65 models feature a 4-channel strobe controller integrated within the GenICam tree and adhere to the GenTL standard for seamless compatibility with existing software. This design makes them highly suitable for both new projects and upgrades of legacy applications.

Conclusion

SVS-Vistek’s HR camera series offers powerful tools for high-resolution imaging across a variety of industrial applications. With their global shutters, advanced sensors, and flexible interfaces, these cameras provide an economical solution for motion analysis without compromising quality or speed.
