Mitsubishi Electric Develops Tomographic Imaging Technology to Visualize Hidden Objects with Millimeter Accuracy

Wednesday, March 29, 2023

Mitsubishi Electric Corporation has recently introduced an innovative industrial tomographic-imaging technology that utilizes a 300GHz terahertz wave. This breakthrough technology enables one-shot, one-direction measurements at any depth, making it ideal for non-invasive scanning of biological organisms and moving objects with high-resolution accuracy in millimeters.

Traditional X-ray scanning devices are primarily used for baggage screening in airports, train stations, and stadiums to detect hazardous materials. Similarly, body-scan systems that employ millimeter waves are typically large-sized and require 180-degree measurements while the subject remains stationary, limiting their usage to airports and restricted public spaces. In contrast, Mitsubishi Electric's solution overcomes these limitations.

The company's pioneering approach combines virtual focus-imaging technology, which employs terahertz waves that have minimal impact on living organisms, allowing for tomographic imaging of objects using a single irradiation in one direction. Additionally, the technology incorporates multi-mode beamforming, which combines multiple images to minimize detection errors. This system is capable of imaging moving targets, including biological organisms, making it suitable for applications such as walk-through security gates and non-destructive scanning on production lines in motion. Moreover, the scanners can be designed in compact sizes, facilitating installation in various locations.

Mitsubishi Electric's advancement in tomographic-imaging technology offers a promising solution for enhancing security measures, improving efficiency on production lines, and enabling non-invasive inspections. With its ability to capture high-resolution images in real-time, this innovative technology has the potential to revolutionize scanning systems across various industries.
