Conformable Organic Photo Sensors for Particle Systems Characterization (original) (raw)
Use the Organic Photo Sensors (OPS) properties to develop method to characterize particle systems Model light scattering in a complex environment (confined space-industrial constraints) to predict the OPS response Invert the collected signal to obtain a bi-univocal relationship between the particle size of the sample and the signal Design an optical particle sizing prototype able to operate in such environment MONTE-CARLO LIGHT SCATTERING MODEL Some assumptions Two parameters distribution (Log-Normal)-Spherical particles Parameters : mean diameter and standard deviation (+index) Scattering regime: simple or multiple Remote sensing approximation Numerical model and computer code Principle : Decompose into probabilities the physical behavior and model [1] Allow to use simultaneously various models and theories:-Optic & physic (Snell-Descartes, diffraction, rainbow, critical scattering…) [2]-Electromagnetic (Lorenz-Mie, Debye…) Angular approach chosen: Intensity vs. collection angle (structure factor) [3] Computer code: Fortran, MPI,… Result example : cylindrical projection of the scattered light by droplets cloud (water droplets in air, D= 100µm
