Abstract

See full text

This disclosure relates generally to an optical strobing based multi-frequency vibration measurement, and more particularly to systems and methods for autonomous stroboscopic machine inspection for multi-point and multi-frequency vibration measurement. Embodiments of the present disclosure provide for an optical strobing based multi-frequency vibration measurement by selecting a strobe frequency, obtaining one or more image frames, obtaining a marker position, calculating a fast fourier transformation, obtaining one or more peak prominent frequencies, obtaining a product set of the one or more peak prominent frequencies, optimizing the strobing frequency where the value of the product set of the one or more peak prominent frequencies is not equal to an optimum pre-defined system value and detecting and measuring a plurality of vibrations of multiple frequencies by applying a chinese remainder theorem on the product set and the strobe frequency set.
