Simultaneous holographic imaging and light-scattering pattern measurement of individual microparticles

Opt Lett. 2016 Jul 15;41(14):3363-6. doi: 10.1364/OL.41.003363.

Abstract

This work combines digital holography with spatial filtering at two wavelengths to record the hologram and light-scattering pattern for a single particle using a color sensor. Particles 30-100 μm in size and with various shapes are considered. The results demonstrate the ability to unambiguously associate a complicated scattering pattern with the particle size, shape, and orientation.
