本发明涉及一种用于相位位置或两个脉冲序列的相位偏移的高精度的测量的设备和方法，不论脉冲频率。 为了这个目的，两个旋转体1和2的旋转角度进行量化，由增量式编码器3和4中的脉冲串变换，然后检测这在至少两个型动物数字计数器5和图6。 从两个计数器值的后续数字减影在加法器7上形成的数字差值结果被转换成数字/模拟转换器8，并通过在一个Tiefpaßfiler9解码到差动旋转角Δ。PHI的连续的模拟信号的装置; 再成形，其被提供到显示设备第十 对于Δ。PHI的进一步的处理;用于确定所述差角速度或每转-proportionalen模拟信号，每角或每个的累积Differenzdrehwinkeis 9时间单元和所述显示装置10被附加地插入在低通滤波器之间的时钟控制存储元件30。 计时可由一单独的时间元件31由旋转编码器3和4中，数字计数器5和6，或默认时间时钟的手段来完成。 由频率计数器32之前的显示装置10的预筛选，频率确定也是可能的。

The invention relates to an apparatus and method for high-precision measurement of the phase position or phase shift of two pulse sequences, irrespective of the pulse frequency. For this, the angle of rotation of two rotating bodies 1 and 2 are quantized, converted by incremental encoders 3 and 4 in pulse sequences, and these then differents in at least two digital counters 5 and 6 detected (Figure 1). The formed from a subsequent digital subtraction of the two counter values ​​in an adder 7 digital difference result is converted in a digital / analog converter 8, and converted by decoding into a Tiefpaßfiler 9 to a continuous analog signal of the differential rotation angle Δφ, which is supplied to a display device 10 , For further processing the Δφ-proportional analog signal for determining the difference angular velocity or the per revolution, per angle, or per unit of time accrued differential angle of rotation a clock-controlled storage element 30 is additionally connected between the low pass filter 9 and the display device 10th The clocking can be done by a separate time element 31 by means of the rotary encoder 3 and 4, the digital counter 5 and 6, or by default a time clock. By prescreening of a frequency counter 32 before the display device 10 also has a frequency determination is possible.
