The median age in the city was 40.9 years. 25.3% of residents were under the age of 18; 5% were between the ages of 18 and 24; 25.5% were from 25 to 44; 31.1% were from 45 to 64; and 13% were 65 years of age or older. The gender makeup of the city was 51.6% male and 48.4% female.

Schlieren was first mentioned in 828. [3] Until 1415, Schlieren belonged to Habsburg. After the conquest of Aargau by the Swiss Confederates it was a component of the county of Baden. In 1803 Schlieren was assigned to the Canton of Zürich. In 1777 the minister Heinrich Keller created here the first "deaf-mute school" in Switzerland.
Schlieren (/ ˈ ʃ l ɪər ən / SHLEER-ən; German: [ˈʃliːʁn̩] ⓘ, German for 'streaks') are optical inhomogeneities in transparent media that are not necessarily visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of such inhomogeneities.
The first application of the N-slit interferometer was the generation and measurement of complex interference patterns. [ 5 ] [ 6 ] These interferograms are accurately reproduced, or predicted, by the N -slit interferometric equation for either even ( N = 2, 4, 6,...), or odd ( N = 3, 5, 7,...), numbers of slits.
A point diffraction interferometer (PDI) [1] [2] [3] is a type of common-path interferometer. Unlike an amplitude-splitting interferometer, such as a Michelson interferometer, which separates out an unaberrated beam and interferes this with the test beam, a common-path interferometer generates its own reference beam. In PDI systems, the test ...
The Mach–Zehnder interferometer is a device used to determine the relative phase shift variations between two collimated beams derived by splitting light from a single source. The interferometer has been used, among other things, to measure phase shifts between the two beams caused by a sample or a change in length of one of the paths.
