本文简单介绍了LVDT、相敏检波器和三角波发生器的工作原理及自行设计的一种实用的LVDT相敏检波读出电路。

The principles of the LVDT, the phase-sensitive detector and the triangular wave generator are briefly illustrated in this paper. A practical LVDT readout.

其线路简单易调整，而性能指标优于或至少不低于电流开关型相敏检波器。

The performances are at least no less than a current-switching PSD, and their circuits are rather simple and easy to adjust.

从结构简单、价廉和实用的角度考虑，近年来，国内外石油勘探和军事反潜等领域提出了研制基于光强度调制原理的水声检波器的想法。

The phase interferometric hydrophone of the all is investigated most extensively, and its applied ranges have extended to the engineering and civil fields instead of the pure military use.
