with laser ray is a good novelty for children and adults
"Cool!", "Fantastic!", "Unbelievable!"
These exclamations, followed by enthusiastic applause, succeed
after each number of the Cosmic Laser Concert, the show
that is running at the Gávea Planetarium, a good option
for recreation for this weekend. For Cr$ 400 you can see
a show that seems to take one to another galaxy: geometric,
multicolored and tridimensional images, projected by a laser
ray equipment, parade in the dome of the Planetarium, sometimes
at a slow pace, others, frenetically, to the sound of music
commanded by an operator. The operator transforms the images
at his own will, shaping them differently and making them
dance to the rhythm of each music.
is created with the projection of images reproducing our
galaxy in the dome. The first luminous points projected
break the almost complete darkness by the laser while the
"Stratosphere" music by Tangerine Dream is played loudly.
The laser is projected in red, yellow, green and blue. Spherical
shapes appear and they spread as sound waves reproduced
has intense color and its focus is precise, reminding neon
lights. The images multiply and are continuously being transformed:
geometric forms, entwined lines, water mirrors, haze; a
ballet of colors and shapes, all parade in the dome, allowing
a numberless of associations by the public.
was brought to Brazil by an American company. Its owner,
Willy Feliu, says the same show is going on for more than
five years at the London and Los Angeles Planetariums, and
it has been exhibited most successfully in the main capital
cities of the world. There is no fixed time for the Rio
de Janeiro season. It will last as long as there is public.
laser is used in the show (these are lasers of neon, helium
and argon), the most adequate for entertainment, due to
its capacity to produce four colors, explains Soraya Bittencourt,
electronic engineer. She is being trained by the North-American
Dexter Goucha, in order to be able, soon, to operate all
the controls of the laser during the show, as Dexter has
to return to USA. According to Feliu, to do this job, it
is also necessary to know music, besides electronics, and
to have sensibility to make the laser "dance" in the adequate
beam, explains Soraya, is divided by prisms and mirrors,
via electronic process. The operator disposes of 57 buttons,
which correspond to dozens of oscillations, with which to
command the figures: - No matter how expert is the operator
- says Soraya - there is no way to repeat a show. They may,
at the most, be very similar, once the range of possible
resources/combinations is unlimited. Besides, the image
is tridimensional. Each person, depending where it is sitting,
will see that image in a different way.
