THREE-DIMENSIONAL IMAGING METHOD AND SYSTEM USING SCANNING-TYPE COHERENT DIFFRACTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20230199162 titled 'THREE-DIMENSIONAL IMAGING METHOD AND SYSTEM USING SCANNING-TYPE COHERENT DIFFRACTION
Simplified Explanation
The patent application describes a method for 3D imaging using scanning-type coherent diffraction. Here are the key points:
- A 2D photodetector is used to detect the diffraction of a coherent beam emitted from a moving light source towards a sample object.
- Multiple 2D diffraction data distributions are obtained by scanning the light source.
- A processor converts the 2D diffraction data distributions into multiple 3D intensity distributions in reciprocal space.
- The processor performs one or more iterations based on a sample function, a light source function, and the 3D intensity distributions.
- A phase-retrieval sample function is obtained through these iterations.
- A 3D reconstruction image of the sample object is generated based on the phase-retrieval sample function.
Potential applications of this technology:
- Medical imaging: This method can be used for 3D imaging of biological samples, such as cells and tissues, providing detailed information for diagnosis and research.
- Material science: It can be applied to analyze the structure and composition of materials in 3D, aiding in the development of new materials with specific properties.
- Non-destructive testing: This method can be used to inspect and analyze objects without causing damage, making it useful in various industries, such as aerospace and manufacturing.
Problems solved by this technology:
- Overcoming limitations of traditional imaging techniques: This method allows for 3D imaging of objects with high resolution and accuracy, overcoming the limitations of traditional imaging methods.
- Non-invasive imaging: The scanning-type coherent diffraction method enables non-invasive imaging, making it suitable for imaging delicate or sensitive samples.
- Fast and efficient imaging: The use of a scanning light source and advanced processing algorithms allows for quick and efficient 3D imaging, reducing the time required for data acquisition and analysis.
Benefits of this technology:

Original Abstract Submitted
in a 3d imaging method using scanning-type coherent diffraction, a 2d photodetector detects diffraction of a coherent beam emitted from a light source that moves in a scanning manner toward a sample object to obtain multiple 2d diffraction data distributions; and a processor converts the 2d diffraction data distributions into multiple 3d intensity distributions in a reciprocal space, performs one or more iterations based on a sample function, a light source function and the 3d intensity distributions to obtain a phase-retrieval sample function, and generates a 3d reconstruction image of the sample object based on the phase-retrieval sample function.
