The application discloses a free surface column lens design method for realizing MEMS uniform light emission, and relates to the field of optical lens design. The method comprises the following steps: a mapping relationship between MEMS light emission energy and a target plane area is established; the vertex coordinates of a free surface generatrix are given, and the coordinates of the rest points on the free surface generatrix are determined according to the mapping relationship; all the points are connected to form the free surface generatrix, and a free surface column lens is constructed based on the free surface generatrix; the lens is arranged between the MEMS and the target plane, and then the light energy reaching each position of the target plane after the exit light beam scanned by the MEMS is refracted by the lens is equal. The MEMS cooperates with the lens to provide a surface structure light with high uniformity and high energy utilization rate for subsequent three-dimensional reconstruction.

The application discloses an optical lens design method, an optical lens, a module, equipment and a storage medium, and belongs to the field of optical technology. The design method comprises the following steps: determining that the lens at the set position of the optical lens is an ideal lens from the object side to the image side along the optical axis direction of the optical lens; acquiring a theoretical discrete phase distribution of a super lens; acquiring a plurality of different incident angle deviation root mean squares of the super lens corresponding to a plurality of different wavelengths respectively according to the theoretical discrete phase distribution of the super lens; if the ratio of the deviation root mean square corresponding to any wavelength to the wavelength is less than or equal to a preset value, it is determined that the nanometer unit of the super lens meets the design requirement; and the ideal lens is replaced by the super lens.
