Modern liquid telescopes have high-tech ways ... In addition to rotating to maintain their parabolic shape, Earth-bound liquid mirrors also rotate around the Earth’s axis, which causes the ...

Also called a "dish" or "mirror," parabolic antennas are used for satellite signals and planetary telescopes. The reflective mirror design can also emit energy such as in a flashlight or ...

To ensure stability and high stiffness, each of the parabolic shaped segments is supported ... three leaf springs which are connected to the fixed telescope structure. The moving frame isolates the ...

For a visible light telescope at a wavelength of 400 nanometers, this means a parabolic mirror needs to have a surface finish that is perfect to within 40 nanometers. That’s the size of viruses ...

This allowed them to form parabolic thin membrane that can be used as the primary mirror of a telescope once coated with a reflecting surface such as aluminum.

The FYST features an off-axis Crossed-Dragone design, consisting of a parabolic primary mirror and a large concave secondary mirror, both with a diameter of roughly 6 meters. This creates a ...

Newton's design combined a parabolic primary mirror for capturing light with a flat secondary mirror, which directed the image to a viewing port on the side of the telescope barrel. Better for ...
