Thank you. As new medical devices are now available. Would be great to UPDATE these video tests. Please show us not only if it can see through (research tools)but can THz penetrate glass? Others show yes it can.

Thank you. Excellent lecture!!! Very nice demonstration of the power of THz.

Maybe something that could better detect fluctuations in temperature, where it is super important, like in the cabin of an aircraft, thanks again

>This wasn't much about Terahertz. It was just a little junior high school standard stuff about the electro magnetic spectrum. Sorry, disappointed.

The THz field is detected via Electro-optic (EO) sampling in a GaP crystal (DelMar Photonics Inc.) using a small percentage of the output of the ultrafastamplifier at 800 nm that is not used to seed the OPA. This crystal is different fromthe one used by Allodi et al.16in that it has a thin EO active layer optically con-tacted to a thicker inactive layer. Specifically, a GaP (110) layer 200 mm thick, andcapable of EO sampling, is optically contacted to a GaP (100) layer 4 mm thick thatis EO inactive. This provides the advantage of pushing etalon features, or recur-rences of the pulse in the time domain, outside the window being scanned. Thisensures that any changes between the sample scan and the reference scan in thetime domain will not lead to artificial signals in the frequency domain. www.researchgate.net/publication/265138100_THz_and_mid-IR_spectroscopy_of_interstellar_ice_analogs_Methyl_and_carboxylic_acid_groups

i want to know what it can not detect?? can it detect kitchenwaste like vegetable peals and tea leaves and others kitchen wastes..

New publication! Terahertz nonlinear conduction and absorption saturation in silicon waveguides arxiv.org/abs/1503.05639 Shanshan Li, Gagan Kumar, Thomas E. Murphy (Submitted on 19 Mar 2015) We employ a silicon dielectric waveguide to confine and concentrate terahertz pulses, and observe that the absorption saturates under strong terahertz fields. By comparing the response between lightly-doped and intrinsic silicon waveguides, we confirm the role of hot carriers in this saturable absorption. We introduce a nonlinear dynamical model of Drude conductivity that, when incorporated into a wave propagation equation, accurately reproduces the observations and elucidates the physical mechanisms underlying this nonlinear effect. The results are numerically confirmed by Monte Carlo simulations of the Boltzmann transport equation, coupled with split-step nonlinear wave propagation.

very good content but poor coordination....in presentation....
