schlieren is the german word for the stringlike optical effect that you observe while dissolving sugar in your tea. You need schlieren optics to magnify these phenomena when these effects are not visible to the human eye.
Thie first thing you notice when you read this article is that schlieren is "not visible" which is a lie as mixing two clear liquids of different densities gives schlieren. The article should be changed to reflect that.
Will be helpful if schlieren photography is included in the flow visualisation section. IMO most of the reader are interested in the technique and having both the articles on the same page will be useful. myth 05:37, 24 January 2007 (UTC)
I'm interested by this, but I've read the article and am still confused. Can someone laymanise this a bit? — Preceding unsigned comment added by 193.63.174.208 ( talk) 11:15, 26 June 2012 (UTC)

It would be great to have a diagram of the imaging system (maybe with raypaths?). I don't understand this well enough to know what would make a good diagram, but I think seeing one would make it clearer to me. HLHJ ( talk) 16:47, 20 May 2014 (UTC)
The article describes things about Schlieren imaging, but there is clear description about what it is how it actually works. Is it a coherent light environment where all the photons passing through the test area travel in a parallel path to each other? — Preceding unsigned comment added by Student342 ( talk • contribs) 01:58, 30 March 2015 (UTC)
There is no mention of Marat, who is well known of course for his contribution to French Revolution, but tried hard to be a scientist and invented the "hélioscope", which was the basis of the Schlieren effect. He even made the demonstration to Benjamin Franklin. Yet, his theories were mocked and he threw everything away and found rage outlet in revolution. https://books.google.fr/books?id=MB3qCAAAQBAJ&pg=PA5&lpg=PA5&dq=schlieren+marat&source=bl&ots=F8DW4JL4lv&sig=Zd2yYElZTneKIcfSpOkN2XMJTAc&hl=fr&sa=X&ved=0ahUKEwjhu_XFsN3TAhXBuRoKHYPQC-8Q6AEIIzAA#v=onepage&q=schlieren%20marat&f=false — Preceding unsigned comment added by Newtoon ( talk • contribs) 08:45, 7 May 2017 (UTC)
Schlieren on YouTube --> this is just a single link to someone's advertisement, and should be a better link. — Preceding unsigned comment added by 78.148.105.53 ( talk) 07:46, 13 July 2017 (UTC)
