Radiographic film system classification and noise characterisation by a camera-based digitisation procedure

Autor: Nicolas Paul, Andreas Schumm, Sebastian Eckel, Uwe Zscherpel, Peter Huthwaite

Extracting statistical characteristics from radiographic films is vital for film system classification and contrast sensitivity evaluation and serves as a basis for film noise simulation. A new method for digitising radiographic films in order to ext

Precision astrometry with SuperCOSMOS

Autor: J. T. Herd, Nigel Hambly, H. T. MacGillivray, W. A. Cormack, Lance Miller

We describe the new, fast, high-precision microdensitometer SuperCOSMOS. Some aspects of hardware and software design that enable high-precision astrometry from photographic plates are explained. We show that the positioning repeatability of the meas

Critical Evaluation of an Automatic Photoplate Processing System for Spark Source Mass Spectra

Autor: Renaat Gijbels, E. Van Hoye, F. C. Adams

Publikováno v: Bulletin des Sociétés Chimiques Belges. 84:595-615

A system for reading and interpreting photographically recorded spark source mass spectra using a computer coupled microdensitometer is discussed. Its essential features are: (1) correction for line width, (2) correction for background, (3) possibili
