WebSep 1, 2024 · In order to save space and achieve the system overall small size and light weight, the optical system output can be placed on a deviation from the sphere center. However, when the beam deviates from the center, it will cause the optical axis pointing error, which needs to be considered in the integrated design of the optoelectronic platforms. WebLens distortion is a deviation from the ideal projection considered in pinhole camera model. It is a form of optical aberration in which straight lines in the scene do not remain straight in an image. Examples of lens distortions are barrel distortion and pincushion distortion, cf.
