Earlier this year, the vision science research group set out on a research task creating a variety of temporal light modulation (TLM) waveforms using an LED, LED driver, and an arbitrary waveform generator (AWG). The waveforms required varying frequencies, modulation depths (MD), and duty cycles, but consistent luminance. The characteristics were chosen to produce a set of TLM patterns for pattern visibility ratings by human subjects. This initially seemed like a straightforward task, as calculation states that keeping the area under each waveform equal yields equivalent luminance. However, reality showed that this approach did not yield the intended results. While keeping the area under the curve for 74 different TLM waveforms constant, the output luminance values differed wildly, with 72% percent variation between the maximum and minimum values To determine the source of the unexpected luminance variation, a simple set up was created to sample both the input and output waveforms simultaneously. Inspiration for the equipment used was partially taken from (Bouroussis et al., 2020). From there, a cycled procedure of generation, validation, and adjustment of waveforms was employed.
