研究目的
Developing a multi-beam X-ray imaging detector for high-speed imaging with high flexibility and low cost.
研究成果
The multi-beam X-ray imaging detector successfully demonstrated four projection images with an exposure time of 1 ms and a high spatial resolution. The setup provides a promising approach for high-speed multi-beam X-ray imaging with high flexibility at a relatively low cost.
研究不足
The spatial resolution of the images was limited by the thickness of the scintillator screen and the diameter of the optical fiber. The field of view is smaller than those obtained by other detectors.
1：Experimental Design and Method Selection:
The detector consists of four scintillator screens connected by a branched optical fiber bundle with a CMOS camera. The setup was designed for multi-beam X-ray imaging with silicon single crystalline blades.
2：Sample Selection and Data Sources:
A USB flash memory was used as a sample for demonstration.
3：List of Experimental Equipment and Materials:
Scintillator screens (Gd2O2S: Tb, 50 μm), optical fiber bundle (SOG-70S 50 μm, SUMITA OPTICAL GLASS, Inc.), CMOS camera (Photron FASTCAM Mini AX50), relay lenses, and optical oil.
4：Experimental Procedures and Operational Workflow:
The scintillator screens were placed on the tops of the branches of the optical fiber bundle. The projected images on the screens were transmitted by the optical fiber bundle to its other end and captured by the CMOS camera.
5：Data Analysis Methods:
The images were analyzed for spatial resolution and depth differentiation.
