Abstract

The Translating Apertures Algorithm (TAA) is a novel method for imaging angular scatter. This paper presents analysis of the TAA using k-space theory, and simulations performed using a simulation tool, PSF. The effective depth of field of the TAA is calculated by analyzing the correlation coefficients between the two acquisition aperture geometries. A correction method is proposed to correct for phase differences in the different system geometries involved, and various commonly used aperture configurations are analyzed for their effect on the TAA
