摘要： An optical element has a member having features which interact with incident light to produce two or more resultant beams. The configuration of the optical element is such that light which interacts with said features when passing through the member from a first side to produce two or more resultant beams does not interact with said features when returned to another side of the member and/or vice versa. The optical element may be used in a readhead of a scale and readhead apparatus.
摘要翻译：光学元件具有具有与入射光相互作用以产生两个或多个合成光束的特征的部件。光学元件的配置使得当返回到构件的另一侧时，当从第一侧穿过构件产生两个或多个合成梁时与所述特征相互作用的光不与所述特征相互作用，和/或反之亦然。光学元件可以用在刻度尺和读数头装置的读取头中。

摘要： The invention provides a rotary device comprising a first rotor rotatable about a first axis and having at its periphery a recess bounded by a curved surface, and a second rotor counter-rotatable to said first rotor about a second axis, parallel to said first axis, and having a radial lobe bounded by a curved surface, the first and second rotors being coupled for intermeshing rotation, wherein the first and second rotors of each section intermesh in such a manner that on rotation thereof, a transient chamber of variable volume is defined, the transient chamber having a progressively increasing or decreasing volume between the recess and lobe surfaces, the transient chamber being at least in part defined by the surfaces of the lobe and the recess; the ratio of the maximum radius of the lobe rotor and the maximum radius of the recess rotor being greater than 1.
摘要翻译：本发明提供了一种旋转装置，其包括可围绕第一轴线旋转并且在其周边具有由弯曲表面限定的凹部的第一转子和与所述第一转子相反旋转的第二转子，所述第二转子围绕平行于所述第一轴线的第二轴线反向旋转，并且具有由弯曲表面限定的径向凸角，所述第一和第二转子被联接以进行啮合旋转，其中每个部分的所述第一和第二转子以这样一种方式相互啮合，使得在旋转时限定了可变容积的瞬变室，所述瞬态室在所述凹部和所述凸角表面之间具有逐渐增加或减小的体积，所述瞬态室至少部分地由所述凸起和所述凹部的表面限定; 凸轮转子的最大半径与凹形转子的最大半径之比大于1。
