摘要
本文叙述了较差视宁度监视仪的基本原理，及云南天文台研制的三个光瞳较差视宁度监视仪，并讨论了各种可能的误差。
The differential image motion monitor(DIMM) with three sub─apertures has been constructed at Yunnan Observatory.The DIMM will be used for site testing of optical /infrared large telescope.The theory of the DIMM is reviewed.Five types of erroes from the instrument noise,the statistial errors,the diameter of sub-apertures,sub-aperture orientations and focusing,for the wavelength variation in the DIMM measurements are discussed.
