For example, under ideal conditions of uniform seismic illumination, the correlation of the noise signals between two seismographs provides an estimate of the bidirectional seismic impulse response.

Other watches use electroluminescent material to produce uniform illumination of the background of the display, against which the hands or digits can be seen.

Since the zonal cavity method only gives an average lighting level, manufacturers tabulate recommended spacing to mounting height ratios that must not be exceeded if uniform illumination is desired.

No lights, merely a uniform illumination of mild, unfocused light.

Wall mounting systems need to be equipped with some form of lighting, designed to achieve uniform illumination on the full plate surface.

They are optimized for working apertures of f/8 to f/11, and for extremely flat field and uniform illumination.

The building also incorporates a design which provides uniform illumination of the interior.

Hidden lights located over and under the overhead bins create uniform and comfortable illumination.

It is the combination of light reflections from various surfaces to produce a uniform illumination called the ambient light.

In practice, the conditions for uniform illumination can be met by placing the source of the illumination far from the aperture.
