title: Stacked-grid Collimators Described with Dimensionless Parameters.
abstract: The properties of a one-dimensional stacked-grid collimator can be specified by two dimensionless parameters. This is useful because a two-dimensional collimator can usually be described as two one-dimensional collimators. Plots are given that show normal-incidence transmission and FWHM angular response in terms of these parameters. Transmission is calculated with Fourier optics instead of the Fresnel-Kirchhoff integral.
