To focus-match or not to focus-match inverse spatially offset Raman spectroscopy: a question of light penetration
Georgina E. Shillito, Lewis McMillan, Graham D. Bruce +1
The ability to identify the contents of a sealed container, without the need to extract a sample, is desirable in applications ranging from forensics to product quality control. On…
Meshless Monte Carlo Radiation Transfer Method for Curved Geometries using Signed Distance Functions
Lewis McMillan, Graham D. Bruce, Kishan Dholakia
Significance: Monte Carlo radiation transfer (MCRT) is the gold standard of modeling light transport in turbid media. Typical MCRT models use voxels or meshes to approximate experi…
Asymmetric longitudinal optical binding force between two identical dielectric particles with electric and magnetic dipolar responses
Xiao-Yong Duan, Graham D. Bruce, Feng Li +1
In general,the optical binding force between identical particles is thought to be symmetric.However,we demonstrate analytically a counter-intuitively asymmetric longitudinal optica…
Measuring picometre-level displacements using speckle patterns produced by an integrating sphere
Morgan Facchin, Graham David Bruce, Kishan Dholakia
As the fields of optical microscopy, semiconductor technology and fundamental science increasingly aim for precision at or below the nanoscale, there is a burgeoning demand for sub…
Measurement of variations in gas refractive index with resolution using laser speckle
Morgan Facchin, Graham David Bruce, Kishan Dholakia
Highly-resolved determination of refractive index is vital in fields ranging from biosensing through to laser range-finding. Laser speckle is known to be a sensitive probe of the p…
Wavelength sensitivity of the speckle patterns produced by an integrating sphere
Morgan Facchin, Kishan Dholakia, Graham D. Bruce
Speckle metrology is a powerful tool in the measurement of wavelength and spectra. Recently, speckle produced by multiple reflections inside an integrating sphere has been proposed…
