找到几个有关描述的英文句子： optic-to-mount interface： This intermediate level course will focus upon a variety of techniques commonly used to mount optical components and to incorporate them into optical instruments. Typical mountings for single and multiple lenses, filters, windows, small mirrors and prisms will be discussed. The latest first-order analytical methods for designing and evaluating the optic-to-mount interface will then be explained and illustrated through practical examples. Important consequences of changing material properties, interface type and part dimensions, as well as the effects of temperature changes and of acceleration forces, will be considered.
Describe common forms of the optic-to-mount interface, including sharp corner interfaces, tangential interfaces, toroidal interfaces, flat bevel interfaces, elastomeric interfaces 从字面理解就是一种光学界面
kinematic interface： The instruments are attached to the primary structure and rely on the primary structure for structural support. Under launch loads, the primary structure will deflect and distort theinstrument interfaces. If the instruments are attached using conventional methods, they will be forced to share some of the loads carried by the primary structure due to differential strains between the primary structure and the instruments. This is highly undesirable since theinstruments are typically delicate structures not designed to carry primary structure loads. It is therefore necessary to isolate the instruments from the primary structure load path. This can be achieved by making the instrument interface statically determinate [1]. This type of interface is called a kinematic interface in which only six degrees of freedom are constrained. Theattachment fittings used in this type of structural interface are called Kinematic Mounts. 好像是2个东东的接触界面。
个人理解： optic-to-mount interface：光学元件与底座的界面 kinematic interface：动态界面，是不是指光学仪器中使用时需要调节的部分？ mounting optics in optical instruments：光学仪器中光学元件的安装 center the lens：透镜居中安装，可能是指光学仪器中的透镜应当同心吧。
