Abstract

We present the results of designing and fabricating distorted diffraction gratings which allow us to map multiple objects, placed along the optical axis of such grating based systems, onto a single image plane. We plan to use the gratings in the alignment of a long optical train, with the intention of simulating part of the beam transport system of a long baseline optical interferometer. The objective is to produce a simple system that will allow for the automatic alignment of the long optical trains within complex systems, such as the Magdalena Ridge Observatory Interferometer.
