[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation method of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0034] see figure 1 , the method of the present invention based on the frequency domain to remove periodic noise in the light field reconstruction image, the steps are as follows: S1: Place the sample in front of the light field imaging system, illuminate the sample with a light source, adjust the imaging plane of the system to the plane where the sample is clearly imaged, and collect Light field image of the sample.
[0035] The principle of the light field imaging system of the present invention is based on a type II light field camera. The light field imaging system includes a main lens, a microlens array and a sensor. The specific imaging process is that the sample A is imaged in front of the microlens array through the main lens,...
