One way of achieving super-resolution is to convert the Guess distribution of the object space into square distribution of that. A special phase-shifting lens is designed for attaining the function. In developing designs for the special phase-shifting lens, algebraic approximate formulas are used to obtain a general understanding of the transition between the Guess distribution and the square distribution. Computer simulation was then used to obtain a detailed performance evaluation. The evaluation results indicated the following: the Guess distribution of the laser light is converted into the square distribution by the special phase-shifting lens.
