Showing papers on "Depth of focus published in 2022"

TL;DR: Based on the radiation pattern of a spatial uniform magnetic current line source (UMLS) antenna, a method for creating a spatial optical tube with a variable length and arbitrary orientation for a 4 π focusing system was proposed in this paper.

TL;DR: In this article, a modified holographic encoding comprising virtual optical elements was proposed to extend the field of focus on a screen tilted by 56°. But the effect of field depth on the image quality and brightness was not evaluated.
