As established by scientific publications, the microscopic study of light scattering—and holographic microscopy in particular—holds tremendous potential. Our team has assembled multiple holographic systems to explore these phenomena and has obtained the first set of systematic measurements.
Our aim is to image particles both near and below the wavelength of light, using unique methods across diverse settings. Because the particles under study are small and many foreign particles may be deposited on the surface being investigated, along with laser light introducing granular noise, we are developing signal amplification techniques to improve accuracy.
This picture shows side by side raw holographic images of three polystyrene particles of different sub-wavelength sizes from different projection distances. We really hunt for the signal in the noise.
