Optical system and optical image processing method using image restoration

An optical image processing method using image restoration, comprising:

• inputting a clear image and a plurality of optical diffraction signals of a testing sample into an image processing device of an optical image system for image reconstruction and predictive recognition;
• placing a testing sample to be examined on a testing platform, and sensing the testing sample via a light source dimmer and a pinhole through an image sensor so as to output the optical diffraction signal;
• extracting a plurality of initial features of the testing sample through an image feature extraction module, extracting a plurality of image features of the optical diffraction signal of the testing sample through a residual network module according to the plurality of initial features, and performing upsampling through an image reconstruction module according to the plurality of image features of the optical diffraction signal extracted by the residual network module so as to restore an original resolution of the optical diffraction signal of the testing sample;
• and
• fusing the plurality of image features of the testing sample through a concatenation module so as to obtain the clear image.
