Abstract

© 2016 IOP Publishing Ltd. Digital holography (DH) methods are of interest in a large number of applications. Recently, the double sideband (DSB) technique was proposed, which is a DH based method that, by using double filtering, provides reconstructed images without distortions and is free of twin images by using an in-line configuration. In this work, we implement a method for the investigation of the mobility of particles based on the DSB technique. Particle holographic images obtained using the DSB method are processed with digital picture recognition methods, allowing us to accurately track the spatial position of particles. The dynamic nature of the method is achieved experimentally by using a spatial light modulator. The suitability of the proposed tracking method is validated by determining the trajectory and velocity described by glass microspheres in movement.
