Abstract

Precision phase measurements are necessary for the laser deformation measurer (LDM), radiofrequency displacement measurer (RDM) and other measuring techniques. The most important parameters of these devices are the frequency range of the measuring, accuracy, dynamic range of the input value (limits of its changing) and leading frequency. In LDM and RDM the demands to these parameters are very tight. The paper discusses the possibilities of the precision fault-tolerant algorithms of the hardware and software devices for these purposes.
