Effect of refractive error in visual tests with sinusoidal gratings
Abstract:
While sinusoidal grating stimuli are finding increasing application in clinical tests for visual disturbance, the possible effects on the test results of simple defocus of the retinal image, due to refractive or accommodative error, are not always acknowledged. Theoretical considerations and experimental measurements emphasize that the degradation in visual performance due to such defocus effects is minimal when the eye pupil is small and the spatial frequency of the grating test objects is low.

Graphical and Analytic Representation of Sinusoids
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...
