详细介绍了石英晶体的原理和使用。 图文并茂，值得研究。-Described in detail the principles and the use of quartz crystal. Detailed descr iption of the more general crystal.

We present the design of a planar-integrated optoelectronic vector-matrix multiplier. The inherent parallel-processing potential is fully exploited by optical implementation of multiplications and summations. Planar integration makes the free-spa
