Description

Technical field: [0001] The invention is a device that utilizes near-field spectral correlation imaging, detection and processing. The system is mainly used for imaging, detecting and processing microscopic and mesoscopic fields in a controllable manner. Background technique: [0002] In the prior art, F. Ferri et al. discussed the mechanism of adding a beam array detection imaging in the article "Differntial Ghost Imaging", that is, intensity correlation imaging improves imaging resolution and quality, microscopic and mesoscopic There are no practical devices in the field of imaging and detection. Summary of the invention: [0003] The purpose of the present invention is to provide a near-field imaging device with intensity correlation, which utilizes the characteristics of the electromagnetic field in the near-field area where both horizontal and vertical fields exist simultaneously, and uses the auxiliary light path to pass classic thermal light source non-local ghost imaging ...
