Dr. Peter Jepsen comments on prior article:" The Truth about Terahertz"


My Note: I had previously posted an interesting article entitled "The Truth about Terahertz" which was originally published here: http://spectrum.ieee.org/aerospace/military/the-truth-about-terahertz
The article highlights the continuing difficulties in moving THz, out of theoretical discussions, and experiments, and finding practical applications. I found Dr. Peter Jepsen's comments found on the Terahertz Community Facebook page to be insightful, and worthy of reposting here, so that readers would have access to his insightful, comments.


Peter Uhd Jepsen I think that this article gives a quite accurate and honest insight in the real state of matters in application-oriented THz research - there are still many wild ideas in circulation that will never work, and it's healthy for the THz community to think a little bit about how we justify our research. I do think, however, that he is too focused on applications that will never work - the real strength of THz radiation lies in my opinion in the fact that it IS a fantastic spectral region for scientific exploration - just because we cannot build T-Ray goggles to look through the clothes of our colleagues does not mean that research and innovation in the THz region is not justified. Clearly, if we cannot look through a kilometer of atmosphere, then why not look at applications that only look through centimeters of atmosphere? Then suddenly many things work again. THz spectroscopy, and in particular THz time-domain spectroscopy with ultrashort THz transients remains a very versatile tool for fundamental investigations in physics and chemistry, and niche applications in industry are being thoroughly tested, for instance by Picometrix.
