摘要：
A novel interferometric technique to measure small wedge angle of transparent windows is proposed. The technique is based on the measurement of the shift of the interference pattern generated by two sheared copies of a laser beam after crossing the optical wedge. A simple lens is used to combine the two beams in their focal plane and measurements are taken for different shears. It is not necessary to perform a spatial filtering of the laser beam since correlations are used to determine the parameters of the experiment. A sample with a wedge slightly greater than one minute is used to illustrate the method.
