Abstract

We demonstrate accurate determination of the size and shape of spherical and spheroidal scatterers through inverse analysis of two-dimensional solid-angle and depth resolved backscattered light intensities. Intensity of scattered light is measured over a wide range of solid angles using a novel scanning fiber optic interferometer from both individual and ensembles of scatterers. T-matrix based inverse analysis of these two-dimensional angular measurements yields completely unique size and aspect ratio determinations with subwavelength precision over a large range of possible scatterer geometries.

FITS system used for experimental measurements. 830 nm low coherence light from a Ti:Sapphire laser (Δ λ = 17 nm) is fiber coupled and then divided between two arms of an interferometer via a highly unbalanced fiber coupler with splitting ratio 99.99% to 0.001%. Arm 1 is mechanically scanned across the back focal plane of the lens in two dimensions, resulting in a variable angle pair θ, φ between delivery and collection rays. Polarization controllers PC1 and PC2 provide control over the collection and illumination polarizations respectively. Reflection signal R1 is path length matched to the sample, while the large path length mismatch between R2 and the sample generates a high frequency interferometric signal that is not measured due to the finite resolution of the spectrometer.

Still image frames from online video clips showing (a) a 0.9 aspect ratio spheroid expanding from 10 μm to 15 μm EVD (Media 1) and (b) a 15 μm EVD sphere being stretched from spherical to 0.7 aspect ratio (Media 2). Still images are for 10 μm EVD with an aspect ratio of 0.9 and 15 μm EVD with an aspect ratio of 0.8 respectively, both PP polarized.

FITS measured scattering from spherical microspheres with equal volume diameter of (a) 15 μm, (b) 10 μm and (c) 6 μm in PP polarization. (d)–(f) Matching T-matrix simulations. In contrast to the 15 μm sphere example, the distribution from the 10 and 6 μm samples illuminated multiple scatterers concurrently, and so were low pass filtered to reduce high frequency interference fringes due to coherent scattering between particles. Note that this frequency is modulation is deterministic in comparison to speckle observed for random scattering phenomena.

Qualitative comparison of FITS (odd rows) and T-matrix simulation (even rows) for a 15 μm EVD (a) sphere, (b) prolate spheroid with aspect ratio 0.92, and (c) prolate spheroid with aspect ratio 0.82 as determined by quantitative image analysis (QIA). The two cross polarized cases are identical and thus presented as a single combined plot. The T-matrix simulations have been masked off at the GRIN lens boundaries to limit their angular extent to match the experimental range.

(b) Experimental data after first stage of registration with common points in simulated data.(c) Simulated data with corresponding points marked. The first round of fitting corrects for a small tilt about the θ = 0 angle, allowing a perpendicular line of points to be selected in the second round.
