Axsun data acquisition board for optical coherence tomography applications


The AXSUN DAQ data acquisition board from Axsun Technologies (Billerica, MA) has a 12 bit 500 MSPs front end configurable with either an external k-trigger or an internal trigger, and integrates with proprietary optical coherence tomography (OCT) swept sources. A Base Camera Link (CL) interface transmits OCT spectral data to image processing electronics. OCT applications include ophthalmology, cancer diagnosis, and pulmonary and gastrointestinal imaging.



Introducing the AXSUN 500MSPS DAQ Board

To meet the performance needs of next-generation Optical Coherence Tomography (OCT) systems, Axsun Technologies introduces a high speed 12-bit Data Acquisition board compatible with Axsun’s high performance swept laser OCT Engine products.

Product Description
The AXSUN DAQ board has a 12-bit 500 MSPs front end, configurable with either an external k-trigger, or an internal trigger, and a base Camera Link® (CL) interface to transmit OCT spectral data to your image processing electronics. The Axsun CL-DAQ card is designed to interface seamlessly with commercial CL Frame Grabbers and provide a straightforward Swept Source upgrade path to Camera based OCT systems.

Convenience and Small Form Factor
The Axsun high speed DAQ board resides in a compact (~114 x 177 x 13 mm) package and is straightforward to integrate with the Axsun Swept Source Engine. The single DC supply, and USB interface allow the user to begin collecting data in a matter of minutes.
