Compound eyes, camera eyes, pinhole camera eyes, even parabolic reflector eyes like a satellite dish.

The five-hundred-kilometer halo around it was something familiar- aflimsy ,slowlyrevolving parabolic reflector, the exact equivalent of the astronomers' orbiting radio telescopes.

Now the group offers a range of different solar cooking boxes, parabolic reflector cookers, solar thermos systems and other devices, including clean cookstoves.

The type of parabolic reflector now in use does not differ essentially from that of an automobile head-lamp, excepting that it is larger.

We'd lie in bed and he'd explain the Doppler effect or parabolic reflectors.

The next postcard was of a parabolic dish antenna.

When parallel light rays hit a parabolic mirror, they all reflect to the same point-thefocal point.

Had the elevation of the parabolic mirror been a few yards higher, none could have lived to tell the tale.

Kerans remembered him building the fire in the laboratory at the testing station, fitting a dented paraboloid mirror around the single filament.
