We discuss different arrangements of rotational shearing interferometers intended for the observation of faint companions to nearby stars. Several methods have been proposed for nullifying the radiation of the star to enable the detection planet. One proposal is the rotational shearing interferometer (RSI). The concept of the RSI is based on the idea of comparing a wave front to a rotated version of the wave front. We analyze different previously proposed arrangements of the RSI and find that some represents different instruments.
