Simultaneously improving multiple imaging parameters with scattering media

TL;DR

This paper demonstrates that adding scattering media to optical systems can simultaneously enhance multiple imaging parameters, such as depth-of-field and aberration correction, offering a simpler alternative to complex optical designs.

Contribution

It introduces a novel approach of using scattering media to improve several imaging parameters at once, unlike traditional methods that focus on individual parameters.

Findings

Depth-of-field was greatly improved.

Spherical, coma, and chromatic aberrations were eliminated.

Potential applications in optical imaging and biomedical fields.

Abstract

Traditional optical imaging systems can provide high-quality imaging with complicated and expensive optical design by eliminating aberrations. With the help of optical memory effect (ME), not independently improving single imaging parameter, but simultaneously improving several imaging parameters by adding scattering media to the imaging systems was demonstrated firstly. As an example, in a simple single-lens imaging system, except the depth-of-field (DOF) was improved greatly, spherical aberration, coma aberration and chromatic aberration were eliminated simultaneously by placing a scattering medium between the lens and the camera. The results indicate the potential applications of scattering media in many fields such as optical imaging, optical measurements and biomedical applications.
