Towards new affordable technologies
As scientific publications have already highlighted, the microscopic study of light scattering, and microscopic holography in particular, has a wealth of potential. Our team has assembled several holographic systems to study these phenomena and obtained the first systematic measurements. Our goal is to image particles near and below the wavelength of light in a unique way in a variety of settings. Since the particles under investigation are small, and since numerous foreign particles are deposited on the surface to be investigated, and the laser light also causes granular noise, signal amplification techniques are being developed.
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.
