Based on the model of integral sampling theory, an important fact about sampled imaging systems is presented in this paper. Instead of the traditional OTF, the complex frequency analysis of the output image with a normal input of bandlimited continuous space speotrum of variable-bandwidth should be used to evaluate the sampled imaging systems acouratly and completely. An evaluation method of aliasing for sampled imaging systems and the theoretical basis of data processing are also presented.
