为了测定运动参数,必须拥有测量长度或角度以及时间的仪器。现行的长度和角度基准只允许以高准确度把单位量值传递给不随时间而变值的量具。在很多情况下,这样做阻碍了运动参数测量技术的发展,首先是角度运动参数——在这个领域中,现在常常要求精密测量角速度的瞬时值。此外,通过相应的角度参数可以确定某些重要的线性运动参 In order to determine the motion parameters, you must have an instrument that measures the length or angle as well as the time. The current length and angle benchmarks allow only the transmission of unit quantities with high accuracy to gauges that do not change over time. In many cases, this precludes the development of motion parameter measurement techniques, above all angular motion parameters - and in this area, it is now often required to accurately measure the instantaneous values ​​of angular velocity. In addition, some important linear motion parameters can be determined by the corresponding angle parameters
