Advances in optical prisms are being used to help researchers gain a greater understanding of space and astronomy

Sydney Institute for Astronomy researchers have developed a new type of wavefront sensor that leverages a ‘photonic lantern’ and deep learning. (Norris et al.)

Lighting the way for astronomy

Researchers have developed a wavefront sensor using a ‘photonic lantern’ that could optimise humanity’s viewing of the cosmos

New terahertz detector could observe galaxies in unprecedented detail

Researchers have developed an ultra-sensitive light-detecting system that could enable astronomers to view galaxies, stars and planetary systems in unprecedented detail

Optical Metrology for Large Space and Terrestrial Telescope Optics

This article is brought to you by: 

Measurement of large optics require metrology systems that can function despite vibration, turbulence and other challenges.Laser interferometry is used throughout the manufacturing of large optics to ensure conformance to demanding design specificationsMore recently, “dynamic interferometry” has been implemented for vibration-insensitive measurement of large optics.
