# Talk:Interferometry

{{helpme}}
Like others on this talk page, I found this article to be surprisingly lame considering the importance of the subject matter. The original article was written by people who were mainly interested in astronomical interferometry, and other applications of interferometry were sort of neglected. Most of the edits over the last few years have been timid additions and corrections compared with what the article really needed in terms of a rewrite. So I decided to try my hand at reorganization. 
What I need is another set of eyeballs critiquing what I've done so far. Am I headed on the right path, or no? And what in tarnation should I do with the awful Interferometry#Imaging interferometry section? I shoved it to the rear, but should I really be splitting it out to its own separate article? Or should I merge it into Astronomical interferometer and let those guys deal with the mess? (not a very nice thing to do ...) Maybe I should just (shudder) delete it?
Also, I removed the "radio-astronomy" template at the bottom. This contributed to the article imbalance. Agree?

Considering the broad impact that this subject has had on many areas of science, there should be a short section on the history of the development of this idea. This is actually the information I hoped to find on this page. 67.222.236.65 (talk) 19:23, 1 February 2014 (UTC)

I'll look into adding a history section. Thanks for the suggestion! Stigmatella aurantiaca (talk) 23:45, 1 February 2014 (UTC)

Providing a link to the White–Juday warp-field interferometer in the "See Also" section implies that this is a type of interferometer that is different than those already listed.  It is not.  It is a Michelson interferometer being used to detect optical pathlength changes that might be caused by changes in "warp fields." I have therefore deleted the reference.

This article is missing the beef on NSA and other agencies use of interferometry for surveillance and electronic warfare. Interferometry involves directing frequencies for active scans of homes, people, brains, effects and the like or even passive scans as energy emits from alternative sources such as electronic devices, over the horizon radar, cell towers, and even human beings (bioelectromagnetic emanations). Interferometry is used to create holographic 3D scans and 3D fields of energy remote from the transmitter. Interferometry has weapons applications, using the energy from transmitters to assault people, do weather modification, house haunting simulations, projections of holograms in the sky and environment, sound creation such as the frey effect and microwave auditory hearing effect, and even alteration of brainwaves based on Robert Malech's 1974 patent, apparatus and method for remotely reading and altering brainwaves (the patent describes using military radar/satellites and interferometry to read and alter brainwaves).
Numerous scientists including Dr. Judy Wood, Dr. Fred Bell, and Dr. Robert Duncan describe interferometry being used from space, land and sea based platforms for these purposes yet the articles are devoid of information on the matter. Military documents and patents and numerous articles also describe such.
NSA whistleblower Russell Tice described in numerous interviews including Russia Today's Breaking the Set with Abby Martin using space capability to spy domestically on Americans, including lawyers, journalists, congressmen, senators judges, banks, and civillians - under classified special access programs, exceptionally controlled information programs, very restricted knowledge programs, and the like.
Based on a review of wikipedia articles it seems as if military applications are being censored and this common knowledge, often even taught at universities, is being kept from public knowledge bases  such as wikipedia.

The Basic Principles section claims that interferometry uses the principle of superposition, yet the lead links to superimposed. Shouldn't this link be changed to superposed? Mysticdan (talk) 17:42, 26 August 2015 (UTC)

@Mysticdan: Good catch! Stigmatella aurantiaca (talk) 00:24, 3 September 2015 (UTC)

Just corrected a serious booboo of mine in the optical flat diagram in the Engineering and applied science section.  Due to 180° phase reversal of the ray reflecting from the bottom surface, while the ray undergoing internal reflection from the top surface undergoes no phase change, constructive interference occurs with path length difference of odd multiples of λ/2, not even. Sorry. --ChetvornoTALK 01:01, 16 December 2016 (UTC)

The qualification linear is often used (e.g. in Boson sampling, second sentence, or in List of types of interferometers), but I cannot find an explanation for it. Could that be added somewhere, please? --H.Marxen (talk) 17:33, 8 May 2017 (UTC)
