We present and experimentally demonstrated a linearly-configured Brillouin optical correlation domain analysis (LC-BOCDA) system that allows large modulation amplitude (Δf) based on a dual probe wave and the control of correlation-order. The adoption of dual probe and the control of correlation-order can suppress the effects of two main origins of the noise - the Brillouin loss of the pump and the beat noise between the pump and probe waves. We experimentally confirm that Δf and the number of resolving points, N, can be increase to 1.8 times without significant noise.
