12-bit High-Speed PCIe ADC Card Available with Optical Coherence Tomography Technology

FMCK Acqiris

Our High-Speed Digitizers Team announces that the U5303A high-speed data acquisition 12-bit PCIe® card, in collaboration with YellowSys, a provider of IP processing firmware and software is now available with an option dedicated to the optical coherence tomography (OCT) technology.

This data acquisition solution uses signal re-sampling which provides on-board enhancement of the range analysis and offers a stable ADC signal sampling cadence. The solution focuses on the clock stability while acquiring the signal in order to avoid sampling cadence changes. This adverse effect on signal acquisition typically occurs when an external k-clock is used. Furthermore, the signal processing is done in real time directly on the data acquisition card, significantly reducing the processing load on the host computer.

The solution was designed using an FPGA, allowing portability of the OCT signal processing IP to other data acquisition cards, including future releases. There is no need for internal circuitry dedicated to OCT, and the easy migration of the processing IP is a key to future OCT technology developments.

“OCT technology is evolving at a fast pace and we strongly believe in supporting developers to push the limits in real-time imaging and quality,” said Didier Lavanchy, operations manager of high-speed digitizers division. “Partnering with YellowSys enables us to meet the application demands using our FPGA development kit.”
