Femtometer-resolved simultaneous measurement of multiple laser wavelengths in a speckle wavemeter
Graham D. Bruce, Laura O'Donnell, Mingzhou Chen +2
Many areas of optical science require an accurate measurement of optical spectra. Devices based on laser speckle promise compact wavelength measurement, with attometer-level sensit…
Deep learning enabled laser speckle wavemeter with a high dynamic range
Roopam K. Gupta, Graham D. Bruce, Simon J. Powis +1
The speckle pattern produced when a laser is scattered by a disordered medium has recently been shown to give a surprisingly accurate or broadband measurement of wavelength. Here i…
Overcoming the speckle correlation limit to achieve a fiber wavemeter with attometer resolution
Graham D. Bruce, Laura O'Donnell, Mingzhou Chen +1
The measurement of the wavelength of light using speckle is a promising tool for the realization of compact and precise wavemeters and spectrometers. However, the resolution of the…
High speed determination of laser wavelength using Poincaré descriptors of speckle
Laura O'Donnell, Kishan Dholakia, Graham D. Bruce
Laser speckle can provide a powerful tool that may be used for metrology, for example measurements of the incident laser wavelength with a resolution beyond that which may be achie…
Optimal compressive multiphoton imaging at depth using single-pixel detection
Philip Wijesinghe, Adrià Escobet-Montalbán, Mingzhou Chen +2
Compressive sensing can overcome the Nyquist criterion and record images with a fraction of the usual number of measurements required. However, conventional measurement bases are s…
