    • A method for identifying and characterizing shape variations in parts. Measurements are taken of a population of parts and the shapes of the parts are expressed as a function having a plurality of coefficients. Discrete or function error maps are developed from the coefficients and a principal components analysis is performed on the error maps to identify the principal components of variation of the parts. The parts may be grouped into sub-populations representing ranges of variation along each of the principal components of variation, and downstream processes may be controlled differently for each sub-population. In one embodiment, a typical (re-generated) part shape is identified along multiple principal components of variation, and a tool path is controlled to be responsive to the typical part shape. Information regarding the principal components of variation may further be used to revise upstream manufacturing processes to advantageously affect the distribution of error in subsequently manufactured parts.
    • 用于识别和表征部件中形状变化的方法。 测量零件的数量,并且部件的形状表示为具有多个系数的函数。 离散或函数误差图是从系数开发出来的,并在误差图上进行主成分分析,以确定部分变化的主要成分。 这些部分可以被分组成表示每个变化主要成分的变化范围的子群体,并且可以对每个子群体对不同的下游过程进行控制。 在一个实施例中,沿着变化的多个主要分量识别典型的(重新产生的)部分形状,并且控制刀具路径以响应于典型的部件形状。 关于变化的主要成分的信息还可以用于修改上游制造过程以有利地影响随后制造的部件中的误差分布。

    • An acousto-optic isolator for a semiconductor laser diode comprises a Fabry-Perot resonator tuned to the laser optical frequency f.sub.o followed by an acousto-optic Bragg diffraction device utilizing surface acoustic waves of frequency f.sub.a launched from a transducer. Light focussed by a lens to the load has a resultant frequency f.sub.o +f.sub.a. Any light reflected from the load suffers a further change in frequency to f.sub.o +2f.sub.a in the diffraction device and hence is blocked by the resonator. Undiffracted light can be detected at a photo-detector and used in a feedback control loop to stabilize the light source to the resonator.
