The primary goal of the SEG Wiki is to … WebA novel solution to problematic ghost images is implemented by using tilted lens elements with polynomial surfaces. Tilting the lens surfaces sends reflections out of the imaging path. The nonrotationally symmetric polynomial surfaces correct aberrations caused by tilts. The complex lens surfaces are fabricated by using gray-scale lithographic patterning of hybrid …
WebMar 27, 2024 · The classical realization of an optical system for the Pepper’s ghost is based on the use of a slanted half mirror, like that in Figure 1 (a). It is simple to realize this arrangement of the optical system; however, the optical system will likely be bulky due to the tilted alignment. WebGhost images in optical systems are faint second images caused by reflections within an optical component.
