Description

technical field [0001] The invention belongs to the technical field of optical imaging and optical detection, and in particular relates to an optical imaging device and method based on quantum statistics. The optical imaging method has high precision breaking through the Rayleigh scattering limit. Background technique [0002] The accuracy with which two objects can be resolved optically is limited by the Rayleigh scattering limit, and its resolving power is related to the wavelength of the light used. If visible light is used as the detection light source, the general resolution accuracy is hundreds of nanometers. However, in various researches and applications at this stage, resolutions with a scale below 100 nanometers are often encountered. In this case, ordinary optical detection methods are powerless. Therefore, a solution is to use various expensive experimental instruments, such as atomic force microscopes, near-field optical scanning microscopes or scanning electr...
