Vision Research, the company behind the Phantom line of high-speed cameras, has announced the new Phantom S991 high-speed camera that uses “CoaXPress-over-Fiber” technology and can shoot 937 frames per second (FPS) at more than 4K resolution.

A new data delivery system

According to the company, the CoaXPress over-Fiber technology allows for more efficient delivery of nine gigapixels every second (Gpx/sec) or 70 Gbps. This translates to 937 FPS at nine-megapixel resolution (4,096 x 2,304) and 52,080 at its lowest resolution (2.048 x16), and multiple resolutions between.

Vision Research states that CXPoF makes use of CXP12 optical fiber and eliminates the need to have multiple CXP6 copper cables. The Phantom S991 only requires two fiber cables as opposed to 16 copper cables that were required by the Phantom S990.

“…The CXP-overFiber technology offers many benefits that support very high throughput. It offers high bandwidth and low latency. It also manages link integration. This technology is affordable and can be scaled up to increase bandwidth.

High-Quality 4K Slow Motion Footage

Vision Research claims that Phantom S991 creates images of “very good quality” and detail using its versatile CMOS sensor. The Phantom Flex 4K’s nine-megapixel sensor supports 12-bit imaging, rolling shutters and global shutters. It also has 6.75 um-sized pixels. This sensor claims that they are more sensitive to light than high-resolution machine vision cameras. It has a daylight ISO rating that is 1,600 monochrome and 400 color with the global shutter.

Vision Research claims that the Phantom S991 does not always need to record in 12-bit. It also offers an 8-bit output option. This allows for higher frame rates at larger resolutions and reduces data throughput.

The S991 uses the same sensor as Flex4K so the quality of footage should not differ. Here is an example of what you can expect from the Phantom Flex4K video.

The Phantom S991 Versus Other Phantom Cams

Although the Phantom S991 may not be the fastest Vision Research camera, it offers a unique set specifications when compared with other cameras in its range. The TMX 7510, for example, can capture 1.75 million frames per seconds and has a 75 gigapixel throughput. The company announced the TMX-5010, a slow-motion camera with a 1.16 million frame per second resolution. It was launched a few months after the 7510.

Both cameras are impressive from a speed standpoint, but they lack resolution. They cannot shoot Full-HD (1,920 x 1,080). The Phantom Flex4K, the company’s best offering, can achieve up to 938 FPS with a 4,096×2,304 resolution. This is slightly more than UHD and cinema4K. The S991 has the same sensor as Flex4K, but is smaller and more flexible. It will be used differently because it uses a different data delivery method. Vision Research classifies the S991 as “machine vision”, which could be used in an industrial inspection or analysis case.
