Abstract
An apparatus includes an x-ray source configured to generate x-rays, at least some of which impinge a sample and at least one diffractor configured to concurrently diffract at least some of the x-rays from the sample in a first direction and in a second direction substantially orthogonal to the first direction. The apparatus further includes at least one two-dimensional (2D) position-sensitive x-ray detector configured to receive at least some of the diffracted x-rays and to concurrently generate first spectral information of the x-rays diffracted in the first direction and second spectral information of the x-rays diffracted in the second direction. The apparatus further includes circuitry configured to receive the first and second spectral information and to generate a single x-ray absorption spectroscopy (XAS) spectrum using the first and second spectral information.
