First experimental results using Singer product apertures

We present the first experimental results obtained using Singer product apertures. We image X-rays scattered from spherical aluminium targets, using a Crypix detector. Despite the relatively low resolution of the apertures, 13 × 13 and 21 × 21 pixels drilled into a tungsten sheet, much higher resolu...

Zusammenfassung:We present the first experimental results obtained using Singer product apertures. We image X-rays scattered from spherical aluminium targets, using a Crypix detector. Despite the relatively low resolution of the apertures, 13 × 13 and 21 × 21 pixels drilled into a tungsten sheet, much higher resolutions are achieved in practice using Fenimore and Cannon’s fine sampling and delta decoding techniques.
