Imaging

Through an optical system an image can be formed. But how to improve its resolution? Is there a limit? Can we reduce the number of optical elements with the same results? Can we even obtain an image without any lens? Here are some questions we are eager to solve.

Wavefront coding in barcode imaging system

For simplicity, it is often assumed that the imaging system consists of a single thin lens. In the case of the barcode reader, the imaging system consists of several thick lenses and ...
