Paper Abstract

Artificial optical stimulation of retinal neurons offers a potentially powerful approach towards the restoration of vision following photoreceptor loss in retinal degeneration. To better realize the potential of this approach, we introduced a holographic wavefront shaping method suitable for power-efficient patterned stimulation of retinal neurons. Here, to advance towards human translation of this technology, we develop and study a holographic interface with the human eye, designed to achieve cellular resolution stimulation in real-time. To this end, we first design and construct an optimized holographic display for high acuity optical retinal prosthesis. Next, we study different speckle-elimination strategies and adapt them to the projection of Sloan letters, a standard visual performance test. Finally, we perform psycho-physical experiments on normally sighted individuals to characterize and validate the performance of our display, and provide evidence for the ability of subjects aided by the display to perform high-acuity demanding visual tasks in versatile spatial and temporal illumination conditions.
