The systematic study and interpretation of the geometric shape, amplitude, frequency, and phase relationships within a repeating waveform, used to extract information about the source or the medium it traveled through.
read more about wave pattern analysis ...Used in electrophysiology (EEG, ERG) to analyze complex biological waveforms, identifying abnormal patterns indicative of disease (e.g., a delayed or reduced B-wave in ERG).
In optics, it is used to analyze the complex shape of an aberrant wavefront, helping to separate the low-order errors from the high-order errors.
By analyzing the current pattern, one can often predict the future state of the wave or the characteristics of the signal source.
A mathematical tool central to wave pattern analysis, which decomposes any complex wave pattern into a sum of simple sinusoidal waves.
OCT uses analysis of the coherence (wave pattern) of reflected light to determine the precise depth and structure of retinal layers.
The position of a point in time (or space) on a cyclical waveform. Phase is critical for analyzing interference and coherence.
