Scientists have demonstrated gravitational coupling between two gold spheres of one millimetre radius, thereby entering the regime of sub-100-milligram sources of gravity
The GEMINI interferometer enables an innovative approach to broadband pump-probe spectroscopy. Thanks to the employed time-domain Fourier Transform (FT) detection system, this configuration permits the measurement of the broadband pump-probe signal with a single-pixel detector and a single-channel lock in amplifier. In this way, it's possible to combine an ultra-broad spectral coverage with an extremely high sensitivity
Thorlabs has expanded its swept source OCT (SS-OCT) offering with the release of Atria systems centred at 1,060nm
In deflectometry, a camera images fringe patterns that have reflected off a surface under test, so that a system can deduce a map of the surface slopes from the deviation of the projected fringes, and from that determine the surface shape. Credit: Mahr
