Abstract
Microdensitometry on neutron radiographs enables quantitative evaluations of images.
The measuring set up presented consists of the Jenoptic Schnellphotometer G III with several essential alterations and extensions. The densitometer was equipped with a photodiode which has a fast and linear response over a measuring range of 6 powers of ten. A travelling table can be moved by step motors in x- and y-directions over an aera of 150 x 250 mm, step length 10 μm. The scanning program is controlled by minicomputer, with a speed of about 5 measurements per second. Data processing and evaluation is done on-and off-line.
Some applications are presented: the examination of several resolution functions, as well as the scanning and fitting for the evaluation of radiographs of the Euratom calibration fuel pin and of the AFNOR IQI and of a proposed L/D standard.
