TLDR
In this article, the first imaging system that combines the high power of terahertz quantum cascade lasers with three-dimensional image reconstruction based on filtered back-projection was presented.Abstract:
Results are presented for the first imaging system that combines the high power of terahertz quantum cascade lasers with three-dimensional image reconstruction based on filtered back-projection. Images of various phantoms have been successfully reconstructed revealing both their external and internal structures.read more
