We present a method for high-frame-rate reconstruction of a dynamic 2-D scene from two effectively continuous orthogonal projections. A natural application of this technique is in the high-speed imaging of transient luminous events-e. g., sprites, elves, gigantic jets, blue jets-in the Earth's atmosphere, where 1-D multianode photometers are used to improve temporal resolution and optical sensitivity over that offered by traditional video cameras. To characterize the performance of the method, we use sprite-image sequences to produce multicolumn and multirow projection data and then use the projection data to produce 2-D "reconstructed" sprite images at the projection data frame rate to compare with the original sprite-image sequence. We also test the performance limits and the spatial resolution of the algorithm using artificially constructed dynamic images.
