Modulation Transfer Function (MTF) is a useful tool for imaging system
performance analysis. It can be used as engineering approach for verification
of main system parameters, or for optimization task of the system under test.
This methodology is based on linear systems theory and allows performance
analysis to be divided into subsystems. In this paper, MTF methodology will
be presented and explained, as an analytical model and as a testing tool which
is implemented in electro-optical laboratory. According to MTF model,
calculations are done to provide theoretical limit for the imaging systems.
After tests in electro-optical laboratory have been done, we compared model
expectations with measurements results and discussed achieved relations. The
measurement has shown that the calculated cutoff frequencies correspond
to the measured ones, in majority of cases. The calculated MTF curve has
proven to be limit for the real measured system performance. Therefore, this
study has shown that MTF can be convenient for finding system limitations,
bottlenecks and increasing the overall performance of the system. Guidelines
for further optimization of the imaging systems are derived.
