Image restorations constrained by a multiply exposed picture
There are a number of possible industrial and scientific applications of nanosecond cineradiographs. While the technology exists to produce closely spaced pulses of X-rays for this application, the quality of the time-resolved radiographs is severely limited. The limitations arise from the necessity of using a fluorescent screen to convert the transmitted X-rays to light and then using electro-optical imaging systems to gate and to record the images with conventional high-speed cameras. It was proposed that in addition to the time-resolved images, a conventional multiply-exposed radiograph be obtained. Simulations were used to demonstrate that the additional information supplied by the multiply-exposed radiograph can be used to improve the quality of digital image restorations of the time-resolved pictures over what could be achieved with the degraded images alone.
