Article Synopsis
- Researchers combined a high-speed external display (360 fps) with an adaptive optics scanning laser ophthalmoscope (AOSLO) to enhance human foveal imaging for psychophysics experiments.
- A custom pupil relay was developed for precise stimulus viewing and was validated to correct refractive errors while achieving a high Strehl ratio, ensuring image clarity.
- The system achieved excellent eye-tracking capabilities, allowing for accurate localization of visual stimuli and capturing detailed images of the human central fovea, while overcoming previous limitations in temporal and spatial resolution.
By combining an external display operating at 360 frames per second with an Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) for human foveal imaging, we demonstrate color stimulus delivery at high spatial and temporal resolution in AOSLO psychophysics experiments. A custom pupil relay enables viewing of the stimulus through a 3-mm effective pupil diameter and provides refractive error correction from -8 to +4 diopters. Performance of the assembled and aligned pupil relay was validated by measuring the wavefront error across the field of view and correction range, and the as-built Strehl ratio was 0.
