Enhanced Frequency Measurement via Lissajous Figure Flipping Periods: A High Precision Approach

Classical frequency measurement techniques, such as direct frequency measurement, multi -cycle synchronous frequency measurement, analog interpolation, time-amplitude conversion, and the cursor method, predominantly rely on hardware, necessitating high hardware standards and potentially leading to measurement errors. These hardware-induced errors pose significant challenges in enhancing measurement precision. To address this issue, a novel frequency measurement methodology employing Lissajous figures is investigated in this study. The frequency of a given signal is obtained by measuring the flipping period of Lissajous figures using a reading frequency approach. As the implementation of Lissajous figures is carried out within the LabVIEW environment, traditional hardware constraints are circumvented, eliminating associated errors and resulting in increased precision in frequency measurement. Moreover, an image matching technique is utilized to accurately determine the flipping period, further improving the precision of the obtained frequency value. The introduction of this innovative method offers a fresh perspective in the field of frequency measurement, enhancing the potential for more accurate measurements. Although continued research is warranted to explore the expansion and refinement of this technique, it holds promise for promoting advancements within the field. This approach demonstrates potential benefits not only for frequency measurement but also for a wide of scientific and
