The deviation caused by acousto-optic tunable filter(AOTF) diffraction in multispectral imaging is analyzed through derivation calculus of the deviation angle.The rotatory polarization of acousto-optic crystal is taken into account in this analysis.The relationships between the polar angle of the incident and the diffracted beams are acquired by using the momentum-matching condition.During the diffraction of the incident beams,far more deviations are induced.
