It was not until the 19th century that the quantitative measurement of dispersed light was recognized and standardized.

A technique for changing the energy distribution of dispersed light from a diffraction grating by altering the shape of the slits.

Walk forward, and one is bathed in the dispersed light that falls on Mr. De Maria's squares and circles as they march down the maple floors.

For this reason, the light produced by a germicidal lamp must be carefully shielded against both direct viewing and reflections and dispersed light that might be viewed.

Now they were under the shadow of the cliff and even the dispersed light of the beam did not reach them; but it did light the hill, the vital shielding hill this side of the fort.
