[0049] The patent of the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.
[0050] In order to verify the conditional part measurement correlation imaging method based on compressed sensing proposed by the present invention, it is now verified through numerical simulation. The wavelength of the pseudo-thermal light source used in this simulation is λ=633nm Gaussian light. In order to describe the performance of the CCPMGI imaging method more objectively and accurately, the present invention introduces a mean square error (MSE) parameter, which represents the degree of deviation between the restored image and the target object. For a target object of size M×N, MSE is defined as:
[0051] MSE ( X i , j , X i , j ′ ) = X 0 ≤ i M X 0 ≤ j N ( X i , j - X i , j ′ ) 2 M X N - - - ( ...
