NIST unblinded me with science: New application of blue light sees through fire

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that ordinary blue light can be used to significantly improve the ability to see objects engulfed by large, non-smoky natural gas fires—like those used in laboratory fire studies and fire-resistance standards testing.
As described in a new paper in the journal Fire Technology, the NIST blue-light imaging method can be a useful tool for obtaining visual data from large test fires where high temperatures could disable or destroy conventional electrical and mechanical sensors.
