The possibility to overcome the limited resolving power of imaging systems beyond the bounds imposed by Abbe's diffraction theory has a long and successful history in applied optics. This article summarizes the main contributions presented along the years and aimed to surpass the resolution limit by providing a general overview to optical superresolution in imaging systems. Special attention will be paid to time multiplexing approaches and, finally, the article will focus on digital holographic superresolved microscopy due to its modern development and wide range of benefits reported in many application fields.
