Measured DCS curve (left) of a calibrated diffuser (INO Biomimic optical phantom, µa = 0.1 cm-1, µs’ = 13.4 cm-1), when rotating at 20 °/s in a transmission geometry. Beta variation (∼3%) due to slight optical nonuniformity across the surface of the diffuser is resolved in a single 50 ms integration time.
