Abstract

Diffraction limit is a limiting factor not only in imaging but also in generating an optical field or illumination. We focus on subdiffraction limit illumination created using a computer generated hologram and its applications. Structured illumination which consists of an array of subdiffraction limit spots or light sheets can be obtained by controlling the phase distribution in the optical field. Performance and properties of subdiffraction limit illumination are discussed. The method has a wide range of applications, and resolution improvement of laser scanning microscopy is presented as an example.
