Pinhole imaging techniques for hard X-rays
Abstract
Numerical image processing techniques have been applied to the restoration of X-ray pinhole photographs of solid targets irradiated by intense relativistic electron beams. An experimentally determined point spread function for the pinhole camera was utilized to eliminate the effects of high energy X-ray degradation of pinhole resolution. Spatially resolved measurements of X-ray yield were made by measuring the dose to calibrated film and calculating the exposure using Monte-Carlo electron-photon transport calculations.
