Cell calibration. (a) Transmission data for the green pixels in the four random regions as function of the PWM duty cycles. δ(∞) = 0 making it trivial to deduce δ from the measured intensity values. (b) The retardation (δ/π) with the fitted values (blue), and the normalized measured intensity with the fitted intensity (orange) as functions of the PWM duty cycle.
