We are pleased to publish the following press release which has been showing on the optical coherence tomography reference website  EXALOS and YellowSys team up with Agilent Technologies’ High-Speed Data Acquisition team to offer high-performance real-time swept source OCT engines.

 EXALOS AG (Switzerland) today announced that it has teamed up with the high-speed data acquisition team of Agilent Technologies Inc. and with the software/firmware team of YellowSys to offer real-time engines for swept source optical coherence tomography (SS-OCT) applications. This SS-OCT engine is an integral system containing a compact swept source module, an FPGA-based data acquisition (DAQ) card in a host PC, and proprietary software that enables real-time OCT signal acquisition, processing, and k-space remapping at an A-scan rate as high as 100 kHz currently.

For research and development, EXALOS is offering a compact PC console containing a miniature OEM swept source, an optical interferometer with an adjustable reference arm, a high-performance low-noise balanced receiver, and a low-speed DAQ card for controlling an external scanner. This real-time SS-OCT engine is on display in a live demo at the EXALOS booth in the South Hall, booth 8431 (BiOS) or booth 431 (Photonics West), respectively.

The FPGA code, the firmware and software of the SS-OCT engine, is delivered by YellowSys, who is offering the code as a stand-alone IP core in combination with an application programming interface (API). YellowSys specializes in customized data acquisition solutions, including adaptations of firmware and software to custom electronics.

“The collaboration with YellowSys and Agilent Technologies allows us to offer real-time SS-OCT solutions to a wider range of customers”, says Dr. Marcus Duelk, CTO of EXALOS. “We are focusing on our core competencies to deliver high-performance broadband light sources and optical sub-systems. Customers can purchase state-of-the-art DAQ cards from Agilent for their OCT systems and have the option to upgrade the card to a real-time SS-OCT engine later on. They can also integrate the existing core of the engine into their own real-time processing environment and into their own software platform, if desired”, says Duelk.

“It’s key to Agilent’s High-Speed Data Acquisition team to be able to collaborate with companies like EXALOS that are at the top of complementary technologies”, says Didier Lavanchy, operations manager for Agilent’s high-speed digitizers group. “With our PCIe card allowing custom signal processing, EXALOS will be able to offer a real-time FPGA-based swept source engine dedicated to high-performance SS-OCT systems. We are looking forward to serving the OCT community and markets.”
