An Extended Maximization Technique for Measuring Optical Constants Using Transmission Gratings in the Soft X‐ray Range
2008
Previous work has shown that careful measurement of the intensity spectra of two or more rectangular transmission grating splaced perpendicularly to the irradiating light can yield enough information to alculate the optical constants of the grating material. In this paper we examine the possibility of estimating the optical constants by rotating a single rectangular grating and observing the angle at which certain of the diffracted orders peak. Assuming this method, we examine the criteria under which it remains feasible and investigate the advantages that can possibly accrue from its use in subsequent experiments designed to measure optical constants in the soft x‐ray range.
