A LCoS phase calibration method and equipment includes: loading the same gray value on each pixel of LCoS, obtaining the initial response relationship of different gray values loaded for many times, combining with the target response relationship, obtaining the corresponding relationship of initial gray value; determining the period K of phase modulation change according to the range of preset gray value corresponding to the target response relationship; According to the corresponding K input gray values, the K output gray values corresponding to the K input gray values are determined according to the corresponding relationship of the initial gray values. The corresponding output gray values are loaded at the K pixels corresponding to the period of phase modulation change, and the actual phase modulation depth is obtained. The modified phase modulation depth is determined by combining the target phase modulation depth corresponding to the target response relationship. According to the initial response relationship and the modified target response relationship, the gray value corresponding to the phase modulation change period K is obtained.
