High-resolution retinal imaging is essential for early detection of ocular and neurological diseases. We present a high-speed swept-source full-field OCT (FF-SS-OCT) system integrated with adaptive optics (AO) and structured illumination using a digital micromirror device (DMD). The system supports both single-mode and multimode illumination for comparative imaging and capable of dynamic projection of line patterns to enhance contrast by separating ballistic and multiply scattered photons. with a B-scan volume rate of 400 Hz and 2.5 ms exposure time. A 25× magnification maps 20 µm camera pixels to 0.8 µm at the sample, with a 308 × 204 µm field of view. This system enables high-contrast, high-resolution imaging for advanced structural and functional retinal studies.
