2. They have a complex construction. Radio telescopes are actually composed of several dozen large, precise antennas instead of a single telescope option. This is necessary because the radio signals they detect are very low in energy. That means an array can demand a lot of land space to be operational. 3.

They use parabolic dishes rather than mirrors. The dish size is larger (up to 100 m) than mirrors of optical telescopes (up to 10 m). Antennas are radio telescopes that not only can receive radio frequency signals but also can Technical issues. Aperture synthesis is possible only if both the amplitude and the phase of the incoming signal are measured by each telescope.

Optical Telescopes. Optical telescopes gather light from the visible wavelength (visible to the naked eye) of the electromagnetic spectrum. They are the oldest and most commonly used telescopes in the world. Perhaps the most important feature of an optical telescope is its light-gathering power, which is a lot higher than that of the human eye.

Now, scientists used radio telescopes observing distant stars to connect optical atomic clocks on different continents. Radio telescopes. detect radio waves coming from space. Although they are usually very large and expensive, these telescopes have an advantage over optical telescopes. 2010-02-06 Our universe is strange, wonderful and vast, says astronomer Natasha Hurley-Walker.
