X-ray film spectroscopy

Mostrar todas las versiones(2)

A multi-pinhole camera using film as a detector is described. Separation of variables in the master-curve sense leads to integral exposure equations which are solved by regularization. A filter-selection method is used to maximize the information content of a given set of measurements. Numerical sim...

A filter-selection method is used to maximize the information content of a given set of measurements.
