Question

A micro-focus 2D x-ray inspection is to be undertaken on a square (8mm x 8mm) mild steel plate of thickness 20mm. The source to detector distance is fixed at 0.5m and the detector is an array 2048 x 2048 pixels and dimensions 100mm x 100mm. The focal spot size of the x-ray tube is 30μm. A geometric unsharpness value (Ug) of better than 0.01mm is required. Calculate the required source to object distance.A micro-focus 2D x-ray inspection is to be undertaken on a square (8mm x 8mm) mild steel plate of thickness 20mm.
