Abstract—It is possible to completely suppress the instrumental error due to the inaccuracy of a diffraction grating, which is realized with an arbitrary shape of the field of interaction between light radiation and topology of the measuring structure. This is achieved by choosing the necessary structure of a encoder, for which the principle of coherence of complementary comb filters formed in the encoders is provided.
