A wavefront sensor is supposed to analyze the phase distribution of a wave without any external reference as used in most conventional interferometric systems. It is shown here that an efficient wavefront sensor can be implemented by an array of two-beam common path inversion interferometers. Each element of the array consists of two Fresnel lenses in a confocal configuration. The wavefront data can be extracted from a superposition of the zero- order, undiffracted wave and the twice diffracted first order wave. The result is a high sensitivity, compact and stable interferometric wavefront sensor.
