A High-Performance Data-Acquisition and Control Module Based on a USB 3.0 Interface for a NIR Broadband Spectrometer

The design and principle of operation of the module for data acquisition and control of a broadband near-IR spectrometer are described. It was developed as the main interface device in the system for visualizing intraocular structures using optical coherence tomography. The achieved performance characteristics of this module make it possible to create a spectral diagnostic optical coherence tomography system with a high resolution value of a few micrometers. The USB 3.0 interface is used as the main computer communication channel, thus providing the compactness, portability, and versatility of the diagnostic system. The data-acquisition system is capable of operating against the background of computationally complex asynchronous procedures for synthesizing a continuous flow of tomographic images in real time, due to which the visualization system can operate in an interactive mode.
