Paper Abstract

Recently, we developed a new type of a shearing interferometer, based on the Mach-Zehnder configuration, except that a beam director is incorporated in one arm of the interferometer and a compensator in the other one. The wave-front displacement is accomplished upon the angle setting between two Risley prisms. With the control of this angle, wave-front displacements are effectuated such that large and small aberrations may be measured with the same instrument. The vectorial shearing interferometer allows the optimization of the measurement parameters tailored to the specific application and the possible absence of available references. We present several applications of the vectorial shearing interferometer to the optical testing and the alignment of the optical systems.
