Distortion is specified as a percentage of the field height. Typically, ±2 to 3% distortion is unnoticed in a vision system if measurement algorithms are not used. In simple lenses, there are two main types of distortion: negative, barrel distortion, where points in the FOV appear too close to the center; and … See more Figure 3shows negative, or barrel, distortion in a 35mm lens system. In this example, all the wavelengths analyzed have almost identical distortion, thus wavelength-related issues are not present. In Figure 4, an … See more In lens datasheets, distortion is usually specified in one of two ways: radial, geometric distortion or RIAA TV distortion.
