Performance comparison of computational ghost imaging versus single-pixel camera in light disturbance environment

TL;DR

This paper compares computational ghost imaging and single-pixel camera performance under various light disturbances, showing SPC generally outperforms CGI and proposing a method to enhance SPC reconstruction in unstable lighting conditions.

Contribution

It provides a comparative analysis of CGI and SPC in disturbed environments and introduces a new method to improve SPC reconstruction with unstable source energy.

Findings

SPC outperforms CGI under similar conditions.

Local light disturbance affects CGI more than SPC.

A new method improves SPC reconstruction with unstable energy.

Abstract

Computational ghost imaging (CGI) and single-pixel camera (SPC) are two types of single-pixel imaging and attracts increasing interest in recent years. The performance differences of CGI and SPC in difference light disturbance environment are investigated. In comparison with CGI, we demonstrate that the quality of SPC is always better in the same conditions and local light disturbance has a larger influence to CGI/SPC than global light disturbance. In addition, a method to improve the reconstruction result of SPC is proposed if the source's energy is unstable and there is light disturbance in the detection process, and its validity is also verified by numerical simulation.
