    Phase compensation is one of the key technologies for pulse compression and ultrashort laser pulse generation. First, we use the phase function of the Fresnel binary phase shaping scheme can achieve a lens-like function, and can introduce a negative secondary spectral phase (negative dispersion) in the frequency domain. Then, the proposed scheme is used to compensate the dispersion of the chirped pulse, thereby turning it into a transformed-limited pulse, and its pulse width is compressed to the time width of the transformed-limited. The proposed scheme is only related to the quadratic phase and does not depend on the spectral amplitude, so it is applicable to various pulse shapes with symmetrical distribution. Finally, the numerical calculation results of common Gaussian pulse and square-wave pulse are given to verify the correctness of the proposed scheme in theory. The proposed scheme provides a new idea and method for chirped pulse compression, and can be extended to other fields related to dispersion compensation.
