摘要： A system for forming an object having a three-dimensional structure, the system comprising: a container for providing a photo-curable material to be polymerized; a rotatable stage for supporting the container; a light source for providing light rays having at least one light pattern to be guided into the container via an optical assembly; a processing unit for determining the light source's degree of non-telecentricity, and determining an optimally pre-distorted set of the at least one light pattern based on at least the photo-curable material's refractive index; correcting at least one distortion of the light rays caused by refraction at the container interface and/or correcting at least one distortion of the light rays caused by non-telecentricity; and whereby the correction of the at least one distortion of the light rays is performed without altering the calibration of the optical assembly.
