A visual representation, typically on an oscilloscope or computer screen, that plots the varying amplitude (intensity) of a signal against the dimension of time or space. This is used to analyze electronic, auditory, or optical signals.
read more about waveform display ...In electroretinography (ERG), the waveform display plots the electrical potential of the retina (A-wave and B-wave) over time in response to a flash of light, diagnosing retinal diseases.
In older OCT devices, the A-scan (a basic signal) showed a waveform display of the reflectivity peaks (amplitude) corresponding to different depths within the retinal tissue.
Can be used to display the profile of the aberrant wavefront itself, showing peaks and valleys that correspond to areas of optical deviation.
The large, positive peak on an ERG waveform display, primarily representing the activity of the bipolar and M?ller cells in the inner retina.
Yes. By plotting amplitude versus time, a waveform display allows the observer to easily visualize the frequency (periodicity) of the signal.
Random, unwanted fluctuations in the signal that appear as jagged, irregular deviations in the smooth waveform.
