New Terahertz Videos on the blog

Image via Wikipedia

A short note, to alert the readers, to two new videos, I've included on the blog, both of which are found below the posts. (I also include my personal commentary, which is based upon my opinion. As noted I am an investor in Advanced Photonix. I will correct any misstatement or misinformation upon
request).




 One new video,  is a video made by Dr. John Federici, at the New Jersey Institute of Technology. http://web.njit.edu/~federici/
There are several blog posts found on this site, which discuss the work being done at the NJIT. It's also worth pointing out that back in 2005,  NJIT purchased a T-Ray 2000, from Advanced Photonix to conduct it's research.

I've also included a new video from TeraView, which discusses non-destructive industrial testing with THz, among other areas, it is using THz. In considering the various videos and Teraherz equipment, I am always struck by how large the TeraView system seems to be in comparison to the Advanced Photonix, T-Ray 4000. Some of you may also find this exchange with Rob Risser, API, CFO, to be of interest, from the API 2009 2nd Quarter conference call:

RANDY KNUDSEN: That's good. And I really appreciate that. Here's a question, and I don't know if this even makes sense, but let me ask it because the question is, is the TeraView system faster or slower? And I guess we really should be asking are we -- when we're talking about their pulse time domain, is theirs faster? Is that a sensible -- .?

ROB RISSER: No, theirs is substantially slower.
RANDY KNUDSEN: Very good.

ROB RISSER: Yes. It is maybe in an order of magnitude slower.

I have absolutely no way to know, if this remains true, (or was true), but I do note that API announced developments to the T-Ray 4000, after this call, indicating they had made it even 10 times faster than it was at that time.

I'm happy to post a response, clarification or refutation, from the scientists at TeraView. I'm looking for commentary, and perhaps this will "stir" some interest.  Bottom line, I'm looking for ways to make comparisons in the various products being marketed, and  better understand the role companies will play in the  huge market which is developing. It's too bad there isn't some way of measuring or comparing the various systems on the market today, in one on one factory setting tests.

I'd also like to point out, that currently, API, is receiving significant funding from multiple US Goverment sources (Department of Homeland Security, IQT, Department of Transportation, & NASA) to make the 

T-Ray 4000, less expensive, even smaller and I believe, even a magnitude more powerful.

Bottomline, is that there is certainly plenty of  room in the virgin THz arena, for a number of companies to participate, and have great success. I certainly wish the folks at TeraView and at NJIT, good luck and future good fortune, in their Terahertz developments.

I hope you enjoy the new videos.

POSTSCRIPT 2/17/11.  In regard to the additional Teraview video I have added, I wanted to share comments posted on Youtube regarding this video.
"The tablet is the blue object picked up by the robot and scanned infront of the THz emitter and detector which on the right of the movie. A laser guage is used to cacluate the size and shape of the tablet to perform the THz scan. For the last several years this equipment has been sold to and is being used by many of the major pharmaceutical companies for tablet inspection to investigate coating thickness and core properties. More information can be seen on Teraviews Website."


BECAUSE TERAVIEW IS NOT A PUBLICALLY TRADED COMPANY, THIS IS THE FIRST TIME I HAVE HEARD THEY ARE ACTUALLY SUPPLYING THz APPLICATIONS FOR COMMERCIAL USE BY THE PHARMACEUTICAL INDUSTRY. I'D LIKE TO KNOW A WHOLE LOT MORE. IN THE FINAL ANALYSIS, THE MORE APPLICATIONS ACTUALLY BEING PUT INTO USE, THE QUICKER THIS VIRGIN TECHNOLOGY WILL GAIN WIDESPREAD ACCEPTANCE.

POSTSCRIPT 2/18/11.  I AM UNABLE TO FIND ANY CONFIRMATION THAT TERAVIEW IS USING IT'S THz APPLICATION, ON THE PRODUCTION LINE OF ANY MAJOR PHARMACEUTICAL COMPANY. SALES FOR LABORATORY USES HAVE OCCURRED, AND PERHAPS THOSE SALES WILL LEAD TO ACTUAL ONLINE QC INSPECTION. IF I AM MISTAKEN, PLEASE SHARE YOUR INFORMATION WITH ME
