Problems solved by technology

However, the existing work used the ideal scalar diffraction theory when modeling the imaging of the light field microscopic system, and did not consider the optical aberrations existing in the light field microscopic system
This will lead to low accuracy of decoupling and reconstructed 3D time-varying information

Abstract

An imaging modeling method and device based on a light field microscopic system, the method comprising the following steps: S1, simulating a microscopic system with corresponding optical parameters through optical design software, and obtaining the optical aberration of the system; S2, obtaining The optical aberration of the system is substituted into the modeling of the point spread function of the light field microscopic system, and the point spread function including the optical aberration of the system is obtained through modeling; S3, the obtained according to the modeling The point spread function models the imaging of the light field micromicrosystem. The imaging model established in the present invention considers the optical aberration of the light field microscopic system, and the modeling is more accurate, which is beneficial to the subsequent three-dimensional reconstruction and obtains more accurate information of the observed object.

Description

technical field [0001] The invention relates to the fields of computer vision and digital image processing, in particular to an imaging modeling method and device based on a light field microscopic system. Background technique [0002] In recent years, brain science has become a research hotspot in the world. The development of miniature microscopes has enabled the visualization of brain activity and structural dynamics in animals during voluntary behavior. However, since the micromicroscope does not have axial resolution, it can only obtain a single, clearly focused picture in the observation field of view when imaging, which limits the further development of visualization. The researchers tried to combine the light field acquisition method and proposed a light field micro-microscope to realize the recording of three-dimensional time-varying information of brain activity under a single exposure. By decoupling and reconstructing the recorded three-dimensional time-varying ...
