Figure 1. Shown here is the same degree of pincushion (a positive geometric distortion) for a 4:3 aspect ratio image and a 16:9 aspect ratio image. The percentage of distortion is visibly greater in ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

The novel distortion matrix approach enables detection of micro-calcifications in breast cancer. These precursors of breast cancer are impossible to detect in the conventional ultrasound image.

For those who are after the ultimate in stills optics, Sigma has just announced a new 14-24mm addition to the Art lens lineup that makes claim to have almost zero distortion. Making claim to have made ...
