Dr. Kaori Fukunaga at NICT has used the T-Ray 4000 to image and analyze Giotto's masterpiece, "Polittico di Badia" (c.a. 1300). This tempera polyptych is known as one of the most important works from the dawn of the Renaissance era, and restoration has just been completed by Stefano Scarpelli in the Uffizi Gallery in Florence, Italy.

Dr. Fukunaga commented on the T-Ray 4000, saying, "THz technologies are progressing very rapidly, and the number of research papers is continuously increasing, but by specialists in optics. This system can convince people that you can use THz imaging off of the optical bench, without struggling to adjust the optical alignment. It's transportable and robust, so that we can bring it to measure precious cultural heritage objects. We would like to welcome potential THz users to 'Try THz imaging.' The words of the conservator, in front of Giotto's masterpiece, says it all: 'That's the thing I wanted to see, and no other technique can show so far.' At NICT, my work is to increase users, both spectroscopy by Fourier Transform-THz and imaging with time-domain THz [like the T-Ray 4000]."

The T-Ray 4000 is designed to meet the requirements of a wide range of markets including: online process control, security, pharmaceutical, medical, aerospace and spectroscopic research.
