A Proposed Method to Measure Dielectric Properties of Non-Spherical Particles Using a Fabry-Perot Interferometer and Multipass Reflective Cell.
Abstract
A method was proposed to investigate the dielectric properties of non-spherical particles in suspension. The system employed resonance shifts of a Fabry-Perot interferometer and beam attenuation of a multipass reflective cell. The theory was developed to support this design and experiments were conducted which verified its feasibility. Zinc oxide particles in suspension acted as a cavity perturbation and did show frequency shifts and attenuation. The method employed wavelengths of 6328A and 10.6 micrometers but can be modified to use a variety of wavelengths and laser power ranges. Although zinc oxide was the only material used the system has the potential to be used with a wide variety of particulate suspensions. (Author)
