​​​​ Introducing ADQ14OCT - A 14-bit digitizer optimized for Swept-Source Optical Coherence Tomography

In this issue you can read about the new high-speed, 14-bit digitizer ADQ14OCT specialized for Swept-Source Optical Coherence Tomography (SS-OCT)

Signal Processing Devices, a manufacturer of high-performance digitizers today announces the release of ADQ14OCT, the latest member of the successful ADQ14 14-bit digitizer family. The ADQ14OCT is optimized for use in SS-OCT applications and contains all features necessary to support the acquisition of cross-sectional and volume images.

The ADQ14OCT digitizer supports a variable-frequency clocking from a laser K-clock starting at 10 MHz and going up to 1000 MHz and high-dynamic range capture of full-bandwidth OCT signals. Acquisition of cross-sectional and volume images are easily controlled using the programmable A-scan and B-scan trigger inputs.

The ADQ14OCT is available with x8 Gen 2 PCI-e interface for very high-speed data transfer to host PC as well as with a USB 3.0 interface for compact designs. It features an embedded and programmable real-time FFT core (up to 32k points).

Since ADQ14OCT is based on high-performance 14-bit analog-to-digital converters, it provides very low spurious errors and low noise which together help enable the highest possible quality of the produced images. It is thus the ideal solution for single-channel SS-OCT instrumentation.

The USB3.0-version of the ADQ14OCT digitizer. Laser K-clock, A-scan trigger, B-scan trigger, and photodetector output signals are connected via 50-Ohm SMA connectors. In addition, the A-scan and B-scan trigger inputs feature programmable input impedances and threshold levels to simplify integration.The ADQ14OCT supports direct streaming to host PC but is also equipped with 2 GByte on-board data memory. The digitizer can easily be programmed with C/C++ as well as Matlab™.
