1.4.4 Point Source / Point Detector arrangement
In exceptional cases with little space and a very small measuring
range, you can also choose an arrangement with point source and
point detector (see Fig. 1-8). The resulting exponential non-linear-
ities in this arrangement can be linearized automatically using a
mathematical function provided by the evaluation unit. The
required tag-specific calculations will be provided by BERTHOLD
TECHNOLOGIES.
