摘要：

We demonstrate a high-speed, image-based tracking scanning laser ophthalmoscope (TSLO) that can provide high fidelity structural images, real-time eye tracking and targeted stimulus delivery. The system was designed for diffraction-limited performance over an 8 degrees field of view (FOV) and operates with a flexible field of view of 1 degrees-5.5 degrees. Stabilized videos of the retina were generated showing an amplitude of motion after stabilization of 0.2 arcmin or less across all frequencies. In addition, the imaging laser can be modulated to place a stimulus on a targeted retinal location. We show a stimulus placement accuracy with a standard deviation less than 1 arcmin. With a smaller field size of 2 degrees, individual cone photoreceptors were clearly visible at eccentricities outside of the fovea. (C) 2012 Optical Society of America
