Abstract
An optical microscope and a method are described wherein a luminescent specimen is located in, and illuminated by, a nodal standing wave field. Luminescence (fluorescence or phosphorescence) is excited in a series of parallel equispaced laminar antinodal zones separated by a series of dark nodal zones that span the specimen. By controlling the node spacing and phase of the standing wave field, a set of luminescence images of the specimen can be observed and recorded. Means can be provided for computing a three-dimensional distribution of light emitters within the specimen from this set of images.
