Vortex is a library for writing high-performance OCT engines in C++ or Python. It is implemented as a modular collection of C++ components with extensive Python bindings. Notable features include online scan pattern generation with time-optimal trajectories, real-time OCT processing with hardware acceleration, synchronized I/O, native support for streaming data to disk in NumPy and MATLAB file formats, and transparent interoperability with NumPy and CuPy. The following presentations and papers have relied on Vortex for their OCT acquisition and processing components.
