Linear arrays of biconcave microlenses have been shown to be capable of imaging small objects using either x rays or neutrons. Because these lenses have small apertures and finite lengths, they are limited in their field of view (FOV). To increase the FOV, we propose that two sets of three-dimensional arrays of these microlenses be used. The spacing of the microlenses is calculated to achieve a complete image with uniform brightness. General design criteria are discussed in situations where either a one-to-one image or a magnified image is required.
