This work describes the imaging of particles using in-line holography. Single particles are confined in an electrodynamic trap and illuminated by a focused laser beam. A CCD camera is used to record the resulting hologram from which an image of the particle is reconstructed computationally. Examples involving a single glass microsphere and multiple Tunisian sand particles are presented.
