Handheld devices are making thermal management in research experiments more accessible, and in turn, advancing applications such as backscattering interferometry
This white paper from Wavelength Electronics details how researchers from Bristol University developed a new ray tracing model, including many parameters not previously reported.

University of Rochester researchers have packaged a way of amplifying interferometric signals using inverse weak value amplification - without increase in extraneous input or 'noise' - on an integrated photonic chip
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

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

Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
