WebDistortion tables, or distortion charts, are tools used to measure distortion levels with certain lenses. Once again, there are two general categories for measuring distortions: Optical and TV distortion. Optical distortion measures the space between where an object appears in a frame versus where it appears in reality, or where it should be. WebACA, along with other aberrations, can be measured two ways. The first as a distance along the optical axis (longitudinal) and the second as a distance perpendicular from the optical axis (transverse). These are shown in figure 1.1b. It’s helpful, when measuring the transverse and longitudinal ray aberrations, to designate abbreviations for ...
