Ratio of the reflected light intensity to the incident light intensity in the retro-reflected scheme. When the incident light is weak ( V 0 = 8 E R ), a beat-like signal appears in the reflected light. When the incident light is strong ( V 0 = 40 E R ), the reflected light signal becomes irregular.
