Other factors being equal, it is found to improve with increase in the theoretical diffraction-limited resolving power of the grating. This characteristic determines the manner in which a given grating should be mounted and used. The reflection echelon, which is essentially a coarse grating, offers one means of improving energy-limited resolution. Limitations which are inherent in a grating made up of laterallyspaced rulings are avoided in a stratified grating-in-depth'', formed by evenly spaced layers of low reflectivity. A similar advantage lies with the Fabry-Perot etalon. Ideally, the energy flux per unit spectral bandpass available with these devices is two orders of magnitude greater than that provided by a laterally ruled grating of the same area. Possibilities and limitations in realizing this gain are considered. en_US dc.format.extent 106201 bytes dc.format.mimetype image/jpeg dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title ENERGY-LIMITED RESOLUTION WITH INTERFEROMETRIC DISPERSING ELEMENTS en_US dc.type article en_US
