A Single Pixel Imaging System Based on Polarization Correlation Imaging

Abstract

The invention discloses a single-pixel imaging system based on polarization correlated imaging. The single-pixel imaging system based on polarization correlated imaging comprises a light source, a modulator, a polarizer, a lens, a polarization analyzer, a filtering sheet, a single-point light intensity detector and a synchronous control and data acquisition module. An emitting end enters the modular through the light source, so that a light field with the light intensity distribution fluctuating randomly is generated, polarization of emergent light is modulated through the polarizer, and the emergent light is emitted to a detection target; the light reflected back through a target object is converged by a receiving end through the lens and the light is converged at the single-point light intensity detector through the polarization analyzer and the filtering sheet; the synchronous control and data acquisition module synchronously controls the emitting end and the receiving end, conducts data acquisition and resolves an association algorithm. According to the single-pixel imaging system based on polarization correlated imaging, the target is detected, identified and imaged through polarization information and intensity correlation of the light, the target detection identification rate and the imaging contrast ratio of traditional correlated imaging are improved, and the system has the advantages of being resistant to complicated background interference and the like.

Description

technical field [0001] The invention relates to the field of target detection, identification and imaging, in particular to a single-pixel imaging system based on polarization correlation imaging. Background technique [0002] Target detection, recognition and imaging have important applications in various aspects such as military detection, intelligent monitoring, and biomedicine. Correlation imaging, or ghost imaging, as an emerging imaging method, has been greatly developed in recent years. Compared with traditional imaging, it has the advantages of single-pixel imaging, no need for spatial array detectors, strong anti-scattering medium interference, and improved imaging resolution. It is playing an increasingly important role in practical applications. However, traditional correlation imaging receives the total light intensity reflected by the target and the background for correlation recovery. When the target is in a complex and wide background, the background light i...

In these cases, traditional correlative imaging is difficult to recover the target information

[0003] Polarization, as another important characteristic of light, is easily ignored in traditional detection or imaging methods because it is not directly perceived by the human eye.
