Advanced Methods for Optical Characterization of Complex Particle Systems
The project deals with optical properties of droplets and particles of “complex” shapes, and whose sizes are beyond a few visible light wavelengths. In this domain, rigorous theories and existing numerical methods cannot be applied to accurately describe light scattering phenomena. We propose a new methodology to calculate the interaction of light with such objects, in parallel to a series of experimental tests for validation. The project includes novel applications in optical metrology, and in optical trapping and manipulation of non spherical particles.
Our main ambitions:
- Development of a novel Ray Theory of Wave (RTW),
- Theoretical and experimental validation of RTW;
- Applications of TRW in the characterization of complex particle system,
- Application of TRW to optical metrology of sprays and bubbly flows;
- Prediction of radiation pressure forces and torques for complex particles,
- Manipulation and trapping of non-spherical particles.
