This conference series has been continually providing forums for promoting the interchange of new ideas on the development of advanced theories and models, as well as the latest experimental developments. Since nearly three decades this series, whose topics are continuously evolving, provides a source of state-of-the-art in light and shaped beam interactions with particle and particle systems. The present edition follows the former Optical Particle Sizing (OPS) and Optical Particle Characterization (OPC) conferences held in Rouen 1987; Tempe, AZ, 1990; Yokohama, 1993; Nürnberg, 1995; Minneapolis, MN,1998; Brighton, 2001; Kyoto, 2004; Graz, 2007 as well as the reformulated LIP conference, held in Rouen in 2012; Marseille, 2014; Xi'an 西安市, 2016 and College Station (TX) in 2018.  The 13th LIP conference, initially scheduled in 2020, was postponed to 2022 due to the covid-19 pandemic.

“Structured fields constructed from superpositions of nondiffracting beams”
In this talk a new technique for creating linear, superficial or volumetric nondiffracting beams and pulses is presented. Constructed from discrete or continuous superpositions of arbitrary-order Bessel beams, it allows both the theoritician and the experimentalist to conceive, design and produce arbitrary-shaped, diffractionless and even dispersion-free structured light fields along lines, surfaces and volumes, even in lossy and dispersive media. Although of wide range of applicability in telecommunications, remote sensing, optical alignment, atom guiding and so on, here we focus on applications in optical manipulation of micro-sized particles and on examples which can be of great interest in volumetric or holographic displays. A historical perspective on the calculation of the beam shape coeffcients of such beams is presented in terms of the recent challenge of finding reliable descriptions of Bessel beams in the context of the generalized Lorenz-Mie theory and with the aid of localized approximation schemes.

“High-contrast imaging through optically dense sprays using Structured Illumination and two-photon excitation Fluorescence imaging”
Imaging and characterizing atomizing sprays is very challenging due to the multiple light scattering generated by the surrounding droplets. This issue has limited the possibility of analyzing liquid breakup phenomena and droplet formation in such scattering media. During the past decade we have been developing, a variety of novel imaging techniques that allows reducing and suppressing image blurs, leading to high contrast visualization of optically dense sprays. These experimental approaches are based on the use of Structured Illumination methods as well as two-photon excitation Fluorescence imaging. Finally, numerical simulations based on GPU accelerated Monte Carlo simulation have also been performed to further understand the effects induced by multiple light scattering and to optimize the proposed optical filtering strategies.

“Holographic Particle Characterization: Unveiling the Composition and Dynamics of Colloidal Dispersions with Holographic Video Microscopy”
The in-line hologram of a micrometer-scale colloidal particle encodes extensive information about the particle's three-dimensional position, its size, its shape and its material composition.  One snapshot can localize a colloidal sphere to within one or two nanometers over a range of hundreds of micrometers.  The same analysis yields the sphere's diameter to within a few nanometers and its complex refractive index to within a few parts per thousand.  No other single technique provides such a wealth of particle-resolved information, especially for undiluted and heterogeneous dispersions.  Implementations based on the Lorenz-Mie theory of light scattering can analyze dozens of holograms per second on  standard computer workstations.  This is fast enough to provide feedback for colloidal synthesis reactions and to control industrial processes. Machine-learning implementations are a dozen times faster.  We will demonstrate these capabilities in applications ranging from time-resolved analysis of single-particle transformations to real-world applications in biopharmaceutical manufacturing and semiconductor processing.

“Tailored optical and acoustic traps for organoid research”
Optical imaging of trapped bio-samples poses a serious challenge for large living specimens, such as developing embryos organoids.
A customized combination of optical tweezers and standing ultrasound waves represents a flexible solution to this problem, facilitating 3D-manipulation and volumetric imaging

In vivo imaging by Spatio-Temporal Optical Coherence techniques

The main physical limitation of the in vivo microscopic imaging is associated with light scattering introduced by irregular and often discontinuous distribution of refractive index. Scattering of light limits the number of ballistic photons delivered to and received from the sample. In our work we try to solve these fundamental physical limitations by developing new optical coherence imaging techniques, which utilize spatio-temporally partially coherent light with access to intensity and phase of detected radiation. In our research activity we focus on developing new optical methods that enable to image biological objects in vivo and in minimally invasive way. We went long way covering significant spectrum of various sizes of objects – from organ-size scale up to internal structure of a single cell.

Publication: special issue of JQRST (SI:LIP2020)

The 13th LIP conference is postponed to 2022 but not the special issue JQSRT-LIP2020 !
Following the highly successful special issues previously published in the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT) [2012, 2014, 2016, 2018],  we are soliciting papers for a LIP2020 Special Issue that you will want your state-of-the-art research to become part of yet another benchmark collection of papers on light and shaped beam interactions with particles and particle systems. This Special Issue will consist only of full-size papers documenting research either reported at the conference or pertaining to the main topics of LIP conferences.  Each submission will be thoroughly reviewed by at least two independent referees to ensure that all accepted manuscripts satisfy the highest standards of scientific quality adopted for JQSRT.  To expedite the communication of your research results to the scientific community, each paper will be officially published (including year, volume, and page numbers) as soon as it has been accepted, typeset, and proof-read. In other words, the authors of accepted manuscripts will see their papers officially published without having to wait for the rest of the manuscripts to get accepted. This accelerated publication protocol is a recent improvement in the JQSRT production process.
  • Gate will open and close: July 15th / October 15th, 2020
  • Code of the special issue: LIP2020
  • Guest editors: Gérard Gouesbet, Fabrice Onofri, Maciej Kolwas, Daniel Jakubczyk
