AI Technical Summary
Existing retinal imaging devices are insufficient in terms of imaging resolution and longitudinal resolution, and cannot effectively distinguish the multi-layered structure of the retina. Furthermore, they are affected by human eye movements, resulting in long image acquisition times and low efficiency.
It employs a line-scanning retinal imaging device, combining confocal imaging and optical coherence tomography (OCT) technology, and utilizes a beam modulation module to achieve eye movement tracking and aberration compensation. High-resolution three-dimensional images are generated through a line-scanning camera and a line-scanning OCT detector.
It achieves real-time eye movement tracking, improves the success rate and image quality of 3D imaging, enhances the cellular resolution of the retina, and reduces the size and cost of the device.
