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 ...

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 ...

Sira Electro-Optics Ltd, the Mullard Space Science Laboratory of University College London and the UK Astronomy Technology Centre in Edinburgh have won a prestigious Faraday Partnership award in ...

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 ...

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 ...

The Very Large Telescope Interferometer (VLTI) at Paranal Observatory has just seen another extension of its already impressive capabilities by combining interferometrically the light from two ...

Every area of interest, particularly if it’s the least bit technical, has its own specialized vocabulary. For example, when the Global Positioning System (GPS) came along and I decided to get a ...

Optical instruments are how we see the world, from corrective eyewear to medical endoscopes to cell phone cameras to orbiting telescopes. The first order optical system design covered in the previous ...

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 ...

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 ...

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 ...

Th emerging field of astrophotonics shows promise in analyzing light from the night sky. Future telescopes, with mirrors half the size of a football field, will need special components to deal with ...
