Real-time digital hologram rendering in ophthalmology faces challenges with high-bitrate image streams. A software called holovibes designed a digital hologram rendering engine, utilizing spatial and temporal signal demodulation operations. It achieves real-time rendering from a 60,000 frames per second stream of 12-bit, 256x256 pixel interferograms, enabling high-quality Doppler imaging and optical coherence tomography (OCT) of the retina. Additionally, sustained real-time 3D OCT image rendering is achieved through short-time analysis of pre-recorded optical interferogram data, transferred at ~7.7 GB/s. Doppler and OCT renderings are done at ~3.8 Giga voxels/s over 512 consecutive frames.
