Progress and Applications of Highresolution and Superresolution Optical Imaging in Space and Biology
Large to observe the boundless expanse of universe with astronomical optical telescopes, small to detect the infinitesimal nanoworld with optical microscopes, optical imaging technology plays a very important role for human beings in the exploration and discovery of the mysteries of the unknown world. To see farther, to see more details and to see more clearly are people′s constantly pursuing goal. The traditional optics theory has proved that all classical optical systems are diffractionlimited, i.e., the physical limit of the spatial resolution of optical systems is determined by the light wavelength and the relative aperture (or numerical aperture) of the system. Can this diffractionlimited barrier be broken through? Is it possible to continue to improve the imaging resolution of optical systems? Around this issue, this paper reviews the recent progress of a variety of highresolution and superresolution optical imaging techniques, and their developments in the fields of space exploration and biological applications.
