Phase position of all points in strip pattern Determination and reproduction method pin real=time

摘要

The method involves using an analogue signal without prior digitalisation results for a phase determination using a phase locked loop circuit (50) provided with electrical components. An analogue sensor signal can be digitalised for the phase determination, and the PLL circuit results using a computer simulation of the electrical components of the PLL circuit. The PLL circuit is applied together with the Fourier transformation method or a phase stepper method, according to the foregoing claims. With a PLL circuit for phase determination, the contour representation and the contour measurement of an object is facilitated in real time.
