Correlation Revival Eigenmodes for Differential Sensitivity in Speckle Metrology
Hal Gee, Morgan Facchin, Graham D. Bruce
Speckle metrology exploits the high sensitivity of scattered fields to parameters of interest, yet this also leaves measurements vulnerable to unintended perturbations. Here we emp…

Ultra-high precision speckle spectrometer enabling radio-frequency scale resolution of atomic spectra
Gabriel Britto Monteiro, Christopher Perrella, Sarah K. Scholten +4
Laser speckle, the granular intensity pattern arising from random optical interference, provides a high-dimensional encoding of spectral information that can be exploited for preci…

Determining intrinsic sensitivity and the role of multiple scattering in speckle metrology
Morgan Facchin, Saba N. Khan, Kishan Dholakia +1
Speckle patterns are a powerful tool for high-precision metrology, as they allow remarkable performance in relatively simple setups. Nonetheless, researchers in this field follow r…
