"Diffraction limit" has been understood for more than two centuries since it was discovered by Ernst Abbe, stating that the minimum lateral resolvable size of any lens-based imaging system is restricted by approximately the half of the illumination wavelength. Recently, with the rapid development and growing demands in many fields such as cell biology, semiconductor industrial, MEMS/NEMS, high precision measurement,…, etc., many novel techniques were developed and implemented in leading to potential establishments of advanced imaging systems with a resolving ability reaching beyond the diffraction limit from several hundreds to less than 100 nanometers. Although these new development are indeed significant as well as diversely influential to scientific breakthroughs, it still lacks of a comprehensive review on how these super-resolution imaging techniques were progressed and how they will be further advanced. Therefore, a comprehensive literature review was performed on the methods being developed and latest advances in super resolution techniques by means of critical analysis, classification and evaluation. Some conclusions were made to provide useful information leading for future development in this field.
