Abstract:
Backlit-pinhole radiography uses a pinhole placed between an x-ray source and a sample. The backlit-multi-pinhole design uses two pinholes on the same substrate, which are separated by a wall, to create two radiographic images projected along similar axes. The wall, a 100-μm thick titanium foil, prevents x-rays generated near one pinhole from exiting the other pinhole. First results indicate that the multi-pinhole target can create two independent radiographs along similar axes. The images are recorded 2 ns apart. Details of our multi-pinhole design and our first results are discussed.
