Optical sparse aperture telescopes utilise an array of smaller, discrete subapertures to synthesise a large effective aperture, thereby achieving high-resolution imaging with reduced system mass and ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.210040, Researchers led by Professor Daewook Kim from The University of Arizona, Tucson, AZ, USA consider advances in optical ...

WASHINGTON, Feb. 5 – Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect. Astronomers are turning to photonic devices ...

Shini talks to us about optical instruments and how they make magnification possible. How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant ...

Refracting telescopes dominated the nineteenth century, with the size of apertures rising to reach the physical limits for lens manufacture at a diameter of around one metre. A key optical development ...

For decades, astronomers have searched for signs of extraterrestrial intelligence using radio telescopes and optical instruments, scanning the skies for artificial signals. Now, researchers are taking ...

Astronomy has always relied on optical instruments, from the early Galilean telescope to fiber-fed spectrographs, so much so that astronomy and modern optics are called astrophotonics. Since ...
