## Overview

OCTSharp is a Windows application for interactive, high-throughput OCT acquisition and imaging. Users configure camera, scan, and processing parameters in the GUI; the application acquires camera frames, coordinates scanner output, processes scans with CUDA, and presents B-scan/en-face imagery and performance data. It can also save raw scan data for later processing. The README documents dedicated GUI, transfer, processing, and display threads. The sampled source confirms the GUI, acquisition setup, processing, CUDA operations, and raw saving; finer thread wiring and some documented capabilities are not visible in the excerpts.
