6. CONCLUSION
In this paper, we examined practical applications of MTF in
the field of photogrammetric cameras. The instrument can measure
camera MTF by adding a few modifications and tools.
It is our hope to use MTF for inspection and maintenance
purposes with periodic tests. Further measurements are needed to
establish performance criteria for future applications.
Proper choice of cameras for specific purposes for the image
quality aspects will be very useful in the future use of cameras
based upon MTF examinations.
This work was done by the support of the Geographical Survey
Institute.
