Problems solved by technology

[0003] With the continuous development of science and technology, people's research on the microscopic world has entered the nanoscale stage from the micron level and submicron level, and the limitation of the optical resolution limit has gradually emerged, which greatly limits the further application of computer micro vision technology.

Although a variety of super-resolution imaging techniques have been realized, the successful implementation of these methods often requires special conditions and hardware support, and the scope of use is limited.
