modulation threshold

[5.9.3] In the case of sine wave grating, manipulation of luminance differences can be specified in terms of modulation, and the threshold may be called the modulation threshold.

modulation = (LmaxLmin)/(Lmax + Lmin)

Periodic patterns that are not sinusoidal can be specified in terms of the modulation of the fundamental sine wave component.
