Paper Abstract

In last year’s session we presented some experimental results from investigations on microscopic scenes with strong light emission such as exploding wires, for which we used laser based shadow imaging methods. The present paper is understood as a continuation in two branches. First, we’d like to discuss the fourier optical properties of shadow imaging in comparison with the imaging of the object itself and its far field, showing that the shadowgraph is the link between imaging the real object and scatterometry. Second, we present investigations on gathering high dynamic range short images of short time processes using a completely different approach based on luminescent screens, delivering a decaying image of naturally high dynamic range, which - during decay time- might be converted to a series of single images under adapted conditions.
