In the few-cycle pulses, the temporal evolution of the electric field sensitively depends on the carrier-envelope phase (CEP). The ability to measure and stabilize the CEP therefore becomes a crucial issue for all applications. However, few studies are focused on the measurement of CEP with coherent linear optical sampling. We propose an efficient method to measure the CEP of the frequency comb pulses by employing a high-resolution linear optical sampling technique. It is shown that constant chirp and pulsewidth of frequency comb pulses have negligible effect on the CEP measurement.
