Title: Innovations of Hongjin Wang in Non-Destructive Testing

Introduction

Hongjin Wang is a prominent inventor based in Changsha, China. He has made significant contributions to the field of non-destructive testing, particularly in the areas of thermal imaging and photovoltaic cell analysis. With a total of 2 patents, his work has advanced the methodologies used in material defect detection and testing systems.

Latest Patents

One of his latest patents is titled "Method and apparatus for single-pixel thermal imaging detection of surface and internal defects of material." This invention provides a method and apparatus for detecting defects in materials using single-pixel thermal imaging. The system includes a laser module that generates uniform laser light, a spatial light modulation module for encoding the light, and a projection lens module that amplifies the encoded light field. The optical convergence coupling module captures thermal radiation from the object, while the thermal infrared single-pixel detector measures the thermal radiation temperature. The image reconstruction module then reconstructs the defect detection results.

Another notable patent is the "Non-destructive testing system and device for photovoltaic cells." This system incorporates a non-contact electromagnetic induction device, a short-wave infrared (SWIR) camera, and a thermal imaging device. The non-contact electromagnetic induction device generates an external electric field that interacts with the photovoltaic cell without direct contact. The SWIR camera and thermal imaging device work together to obtain optical and thermal radiation distribution maps, which are processed by an image processing device.
