共焦显微镜和白光干涉法是分析技术和生物样品三维微结构的两种很有前途的方法。对于这两种方法，通过致动器扫描样品通过聚焦位置。获得了大量的强度帧序列。这些数据用于地形的最终计算。我们证明了在现代Intel微处理器中实现的多媒体扩展(MMX)指令集可以用于有效的实时预处理和快速求值算法。因此，即使在标准的计算机技术上，这种新技术也能够以可接受的运行时间实现更复杂的算法。讨论了用于共焦显微镜和白光干涉测量的MMX指令集的可能性。
Confocal microscopy and white-light interferometry are two promising methods for the three-dimensional microstructure analysis of technical and biologic specimens. For both methods the specimen is scanned through the focus position by means of an actuator. A large series of intensity frames is acquired. These data are used for the final calculation of the topography. We demonstrate that the multimedia extended (MMX) instruction set, which is implemented in modern Intel microprocessors, can be used for effective real-time preprocessing and for fast evaluation algorithms. So this new technique enables the implementation of more-complex algorithms with acceptable run times even on standard computer technology. The possibilities of the MMX instruction set are discussed for confocal microscopy and for white-light interferometry.
