摘要： The effectiveness of a method for checking for exact alignment of two successive shafts, axles or the like is improved by the fact the no measures with respect to linearization or temperature compensation are necessary any longer by using a light-sensitive array as the light-sensitive sensor. The effects of outside light and reflections can be suppressed. The cross section and the quality of a detected laser beam can be checked especially by visual inspection. Production of the corresponding device for executing this process is facilitated. By using matched beam splitters and reflectors as well as light sources of different colors the number of optoelectronic sensors necessary can be significantly reduced.

摘要： Method for nondestructive and contact-free detection of faults in a test specimen which is moved relative to a probe that detects a periodic electrical signal having a carrier oscillation whose amplitude and/or phase is/are modulated by any fault in the test specimen. The probe signal is filtered and sampled by a triggerablie A/D converter stage to obtain a demodulated digital measurement signal which is filtered using a digital frequency-selective adjustable second filter unit to obtain a useful signal which is evaluated to detect a fault in the test specimen. The A/D converter stage is triggered at a fraction of the frequency of the carrier oscillation selected as a function of the fault frequency obtained as the quotient of the relative speed between the test specimen and the probe and the effective width of the probe, and the frequency-selective second filter unit is adjusted as a function of the fault frequency.
