CT beam types have included parallel beams, fan-beams, and cone-beams.

To mask the two large parallel beams that were necessary to support the heavy roof, the architects enmeshed them in crisscrossed steel.

Because of this, parallel beams can be induced to converge or diverge.

Here's the answer: Build a new, stronger, wider bridge with parallel beams that span the whole river, as is done everywhere else today.

There was dark green shade shot with tight parallel beams of white gold.

A parallel beam is described as a group of straight and parallel 'rays'.

Conversely a parabolic mirror can be used behind a spotlight to project a parallel beam from a point source of energy.

The device uses two hyperbolic mirrors to concentrate light rays in a parallel beam.

The construction of the flat screen is inherently very complex because so many parallel beams are required to fill out the image area.

The Bonnor beam can be generalized to several parallel beams traveling in the same direction.
