Spectral Analysis

Interesting technology Patrick. I'm surprised that the base imaging system they used is a Canon 40D. As a kid I worked in a scientific instrument plant (Simpson) that built flame photometers so the nondestructive nature of this process rings some cognitive bells for me. I wonder if there are some other applications of the process that could become "cloud" based?

Cheers

Multispectral textile dating process

The article here shows some very old laundry being inspected using a novel technique: https://www.theguardian.com/culture/...P=share_btn_fb
The process is described here:

This was brought to my attention by Sue Richardson, married to David Richardson and authors of the book Qaraqalpaqs of the Aral Delta.
The upshot is a potential tool for dating textiles, including the possibility of applications on textiles of more recent origin than carbon dating is useful for. There would obviously need to be a tremendous amount of research done on currently accurately dated materials in order to generate a reasonably large database to allow it to be used for the objects of our interest.
