Abstract

We used the flicker ORG method with a variable frequency stimulus to measure the frequency characteristics of photoreceptor activity. Data are collected using a Spatio-Temporal Optical Coherence Tomographic (STOC-T) system. We use a white-light LED for stimulation, which is driven by a linear chirped signal (5 Hz to 45 Hz). This approach allows much faster response measurements across the available spectrum than performing data acquisition at individual frequencies.
