    • An optical device for characterizing a test surface combines a Fizeau interferometer with a polarization frequency-shifting element. Two substantially collinear, orthogonally polarized beams having respective frequencies differing by a predetermined frequency shift are generated by the polarization frequency-shifting element and projected into the Fizeau optical cavity to produce a pair of test beams and a pair of reference beams, wherein the beams in each pair have orthogonal polarization states and have frequencies differing by the predetermined frequency shift. A second, substantially equal frequency shift is introduced in the Fizeau cavity on either one of the pairs of test and reference beams, thereby generating a four-beam collinear output that produces an interferogram without tilt or short-coherence light. The invention may also be implemented by reversing the order of the Fizeau cavity and the polarization frequency-shifting element in the optical train.
    • 用于表征测试表面的光学装置将Fizeau干涉仪与偏振频移元件组合。 通过偏振频移元件产生具有不同频率预定频移的两个基本上共线的正交偏振光束,并投射到菲索光学腔中以产生一对测试光束和一对参考光束,其中光束 每对具有正交偏振状态并且具有与预定频移不同的频率。 第二个基本上相等的频移在Fizeau腔中的任一个测试和参考光束中被引入,从而产生产生没有倾斜或短相干光的干涉图的四光束共线输出。 本发明还可以通过使光纤列中的Fizeau腔和极化频移元件的顺序颠倒来实现。

    • The process for laying a non-full width course of fiber composite tape in a part is designed to ensure that all of the scrap portion of the tape surrounding the non-full width course is deposited in the scrap area and not in the part. An extra cut is made in tape downstream of the non-full width course, between the non-full width course and next course. After the tape head attempts to lay the scrap in the scrap area in the forward direction, the tape head makes a pass in the scrap area with the tape feed and the tape head moving in the reverse direction, and the scrap is laid beginning from the portion of the tape having the extra cut, and progressing to the non-full width course. The method may be used to remove scrap from around non-full width courses having any shape.
    • 将纤维复合带的非全宽度路线放置在部件中的过程被设计成确保围绕非全宽度线的带的所有废料部分都沉积在废料区而不是部分中。 在非全宽度路线的下游,在非全宽度路线和下一个路线之间进行额外的切割。 在磁带头试图将废料在向前方向上放置在废料区域中之后,带头在带进料和带头沿相反方向移动的同时在废料区域通过,并且废料从 磁带的一部分具有额外的切口,并且前进到非全宽度。 该方法可用于从具有任何形状的非全宽度路线周围去除废料。
