UANews Features David Brady, "A New Method for Creating 3D Images"
This image of waterbugs swimming is created using data from a "sparse holography" microscope. The image is three-dimensional. To represent the 3D aspects using 2D images it is shown in "slices" of images. The z position of each slice is indicated in the bottom right corners of each slice-image. At z=0 you can see the noise from the reconstruction process. The upper right bug is closer, so it appears in the closer z frames (z=0.02mm), the bug in the lower portion appears more clearly at farther ranges (z=2.00mm).
David Brady
David Brady, who built the world's first gigapixel camera, has developed sparse holography, a revolutionary technology to create three-dimensional images. The images he creates using this technology are not photographs; rather, they are three-dimensional representations of the scene. A person can view it in high detail using interactive software or by 3D-printing a model. Read the UANews article. Brady's work on sparse holography earned him Optica's 2023 Emmett N. Leith Medal.
