Table 1.
Contrast and amplitude (voltage/threshold) generated by 100 μm, 40 μm and 20 μm pixels for the smallest resolvable C (gap width = 1.2× pixel size) under 3 mW mm−2 irradiance, with 9.8 ms pulses at 30 Hz repetition rate. Stimulation thresholds are 11.7 mV and 19.7 mV in the best and the worst cases, respectively.
