Vision Research, a leading manufacturer of digital high-speed imaging systems, brings extreme throughput to machine vision applications with the introduction of the Phantom® S991 Machine Vision camera. The Phantom S991 employs CoaXPress-over-Fiber technology to deliver up to 9 Gpx/sec (70 Gbps). This throughput translates to over 900 frames per second (fps) at a full 9 Mpx resolution of 4096 x 2304 and over 52,000 fps at lower resolutions, including 2304 x 16.

The Phantom S991 offers users very high quality, detailed images. The 9 Mpx sensor in the S991 is the same sensor used in Vision Research’s renowned high-speed media camera, the Phantom Flex 4K. The sensor has 12-bit imaging and provides both rolling and global shutters to meet a variety of application needs. Also, its 6.75 μm pixel is larger than many high resolution machine vision cameras, translating into higher light sensitivity, with a daylight ISO rating of 1,600 for monochrome and 400 for color in global shutter.

Additionally, the Phantom S991 is designed to achieve very high frame rates and throughput by using CoaXPress-over-Fiber (CXPoF), the latest innovative machine vision protocol. CXPoF uses CXP12 and optical fiber, eliminating the need for multiple CXP 6 copper cables. The Phantom S991 requires just two fiber cables, as opposed to the 16 copper cables required by its predecessor, the Phantom S990. The Phantom S991 has an 8-bit output option to provide higher frame rates in the larger resolutions and reduce data throughput, and it has resolution increments of 128 horizontal x 8 vertical, allowing the user to maximize the resolution for the required frame rate.

“The Phantom S991 with CXP-over-Fiber technology brings significant benefits to machine vision applications,” explains Dan Hafen, Director of Business Development for Machine Vision at Vision Research. “It leverages Vision Research’s industry leadership by offering high quality images at extreme frame rates in a simple, user-friendly package. Furthermore, the CXP-over-Fiber technology provides many benefits to support extremely high throughput. It has a high bandwidth, low latency, manages link integration, and is poised for future bandwidth increases, all while using common, low-cost components.”
