Abstract
A parallel-beam optical tomography system for imaging an object of interest includes a parallel ray beam radiation source that illuminates the object of interest with a plurality of parallel radiation beams. After passing through the object of interest the pattern of transmitted or emitted radiation intensities is magnified by a post specimen optical element or elements. An object containing tube is located within an outer tube, wherein the object of interest is held within or flows through the object containing tube. A motor may be coupled to rotate and/or translate the object containing tube to present differing views of the object of interest. One or more detector arrays are located to receive the emerging radiation from the post specimen magnifying optic. Two- or three-dimensional images may be reconstructed from the magnified parallel projection data.
