Paper Abstract

Against those problems discovered using single-slit to measure OTF, this paper puts forward the time space filtration method to restrain these noise. Experiments verify that the method has gained better effects. Using CCD to measure other parameters, it also has very good reference value. Increasing the sample times can gain better filtration effect. But the time space filtration of long time and multiposition is not very meaning to the raising of measurement. Compare many filtration times, we find that average of time filtration for 8 frames pictures and space filtration for 20 lines is suitable. This experiment results accord with related theory.
