用理想倍率元件进行匹配，对4种液体光学补偿通用构架模型分析推导，得出如单液面、双液面、液体中的反射及透射等诸多平行光路中补偿光学结构的数学模型。设计和演变的光学结构是在液体中置反射镜，光线两次通过液体自然表面，再与理想倍率的平板或施密特棱镜匹配所构成的，水平定向和坡度定角精度能够达到0.01″。给出液体补偿方式匹配表对文中未举例的其他液体光学补偿结构的构成和演变方式具有指导意义。最后对设计的结构补偿误差进行分析和实验验证，给出水平补偿曲线、横摆补偿曲线和像旋补偿曲线。

Incorporating with ideal magnification element, the universal model for four kinds of liquid optical compensation were analyzed and derived. The mathematical models of reflection and transmission in liquid for optical compensation were acquired. The ray passed through the liquid surface twice due to the mirror in the liquid, which contributed to the designed optical configuration matching with the plane plate or Schimitt prism of ideal magnification. The horizontal and gradient directional accuracy achieved 0.01″.The liquid compensation matching table was given, which can be used for other liquid compensation comfigurations. Finally,the compensation error of the designed configuration was analyzed and verified by experiments, the horizontal compensation curve, yawing compensation curve and image rotation compensation curve were given.
