Title: Universal parameter to describe the reduction of refraction effects in the scattering of absorbing spheres

The scattered intensity from large spheres with a real part of the refractive index ofn=1.33,1.5,2.0is investigated as the radiusRand an imaginary part of the refractive indexκ<#comment/>are varied. It is shown that the product ofκ<#comment/>and the size parameterkR,κ<#comment/>kR, is a universal parameter describing the quenching of the refraction phenomenon of the scattered light: the refraction hump, the generalized rainbows, and the glory. The physical reason for this is thatκ<#comment/>kRis the inverse of the relative skin depth of light penetration into the sphere, which is demonstrated by calculations of the internal fields that darken universally asκ<#comment/>kRincreases.

  1. Properly interpreting lidar (light detection and ranging) signal for characterizing particle distribution relies on a key parameter,χ<#comment/>p(π<#comment/>), which relates the particulate volume scattering function (VSF) at 180° (β<#comment/>p(π<#comment/>)) that a lidar measures to the particulate backscattering coefficient (bbp). However,χ<#comment/>p(π<#comment/>)has been seldom studied due to challenges in accurately measuringβ<#comment/>p(π<#comment/>)andbbpconcurrently in the field. In this study,χ<#comment/>p(π<#comment/>), as well as its spectral dependence, was re-examined using the VSFs measuredin situat high angular resolution in a wide range of waters.β<#comment/>p(π<#comment/>), while not measured directly, was inferred using a physically sound, well-validated VSF-inversion method. The effects of particle shape and internal structure on the inversion were tested using three inversion kernels consisting of phase functions computed for particles that are assumed as homogenous sphere, homogenous asymmetric hexahedra, or coated sphere. The reconstructed VSFs using any of the three kernels agreed well with the measured VSFs with a mean percentage difference<<#comment/>5%<#comment/>at scattering angles<<#comment/>170∘<#comment/>. At angles immediately near or equal to 180°, the reconstructedβ<#comment/>p(π<#comment/>)depends strongly on the inversion kernel.χ<#comment/>p(π<#comment/>)derived with the sphere kernels was smaller than those derived with the hexahedra kernel but consistent withχ<#comment/>p(π<#comment/>)estimated directly from high-spectral-resolution lidar andin situbackscattering sensor. The possible explanation was that the sphere kernels are able to capture the backscattering enhancement feature near 180° that has been observed for marine particles.χ<#comment/>p(π<#comment/>)derived using the coated sphere kernel was generally lower than those derived with the homogenous sphere kernel. Our result suggests thatχ<#comment/>p(π<#comment/>)is sensitive to the shape and internal structure of particles and significant error could be induced if a fixed value ofχ<#comment/>p(π<#comment/>)is to be used to interpret lidar signal collected in different waters. On the other hand,χ<#comment/>p(π<#comment/>)showed little spectral dependence.

  2. Cross-platform observing systems are requisite to capturing the temporal and spatial dynamics of particles in the ocean. We present simultaneous observations of bulk optical properties, including the particulate beam attenuation (cp) and backscattering (bbp) coefficients, and particle size distributions collected in the North Pacific Subtropical Gyre. Clear and coherent diel cycles are observed in all bulk and size-fractionated optical proxies for particle biomass. We show evidence linking diurnal increases incpandbbpto daytime particle growth and division of cells, with particles<<#comment/>7µ<#comment/>mdriving the daily cycle of particle production and loss within the mixed layer. Flow cytometry data reveal the nitrogen-fixing cyanobacteriumCrocosphaera(∼<#comment/>4−<#comment/>7µ<#comment/>m) to be an important driver ofcpat the time of sampling, whereasProchlorococcusdynamics (∼<#comment/>0.5µ<#comment/>m) were essential to reproducing temporal variability inbbp. This study is a step towards improved characterization of the particle size range represented byin situbulk optical properties and a better understanding of the mechanisms that drive variability in particle production in the oligotrophic open ocean.

  3. The optical phaseϕ<#comment/>is a key quantity in the physics of light propagating through a turbulent medium. In certain respects, however, the statistics of the phasefactor,ψ<#comment/>=exp⁡<#comment/>(iϕ<#comment/>), are more relevant than the statistics of the phase itself. Here, we present a theoretical analysis of the 2D phase-factor spectrumFψ<#comment/>(κ<#comment/>)of a random phase screen. We apply the theory to four types of phase screens, each characterized by a power-law phase structure function,Dϕ<#comment/>(r)=(r/rc)γ<#comment/>(wherercis the phase coherence length defined byDϕ<#comment/>(rc)=1rad2), and a probability density functionpα<#comment/>(α<#comment/>)of the phase increments for a given spatial lag. We analyze phase screens with turbulent (γ<#comment/>=5/3) and quadratic (γ<#comment/>=2) phase structure functions and with normally distributed (i.e., Gaussian) versus Laplacian phase increments. We find that there is a pronounced bump in each of the four phase-factor spectraFψ<#comment/>(κ<#comment/>). The precise location and shape of the bump are different for the four phase-screen types, but in each case it occurs atκ<#comment/>∼<#comment/>1/rc. The bump is unrelated to the well-known “Hill bump” and is not caused by diffraction effects. It is solely a characteristic of the refractive-index statistics represented by the respective phase screen. We show that the second-orderψ<#comment/>statistics (covariance function, structure function, and spectrum) characterize a random phase screen more completely than the second-orderϕ<#comment/>counterparts.

  4. We present a performance analysis of compact monolithic optomechanical inertial sensors that describes their key fundamental limits and overall acceleration noise floor. Performance simulations for low-frequency gravity-sensitive inertial sensors show attainable acceleration noise floors on the order of1×<#comment/>10−<#comment/>11m/s2Hz. Furthermore, from our performance models, we devised an optimization approach for our sensor designs, sensitivity, and bandwidth trade space. We conducted characterization measurements of these compact mechanical resonators, demonstratingmQ-products at levels of 250 kg, which highlight their exquisite acceleration sensitivity.

  5. We show that for spherical particles greater than ca. 5 µm, the differential scattering cross section is only weakly dependent on the real and imaginary parts of the refractive index (m=n+iκ<#comment/>) when integrated over angle ranges near37±<#comment/>5∘<#comment/>and115±<#comment/>5∘<#comment/>, respectively. With this knowledge, we set up an arrangement that collects scattered light in the ranges37±<#comment/>5∘<#comment/>,115±<#comment/>5∘<#comment/>, and80±<#comment/>5∘<#comment/>. The weak functionality on refractive index for the first two angle ranges simplifies the inversion of scattering to the particle properties of diameter and the real and imaginary refractive indices. Our setup also uses a diamond-shaped incident beam profile that allows us to determine when a particle went through the exact center of the beam. Application of our setup to droplets of an absorbing liquid successfully determined the diameter and complex refractive index to accuracies ranging from a few to ten percent. Comparisons to simulated data derived from the Mie equations yielded similar results.
