Ludwig Mach (8 November 1868 Prague – September 1951) was an Austrian physician and chemist. Building on the work of Ludwig Zehnder in 1891, Mach added refinements to an instrument which became known as the Mach–Zehnder interferometer. He went on to employ photography for collecting visual data streamlines in the field of Aerodynamics. [1]
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.
The Mach number is named after the physicist and philosopher Ernst Mach, [3] in honour of his achievements, according to a proposal by the aeronautical engineer Jakob Ackeret in 1929. [4] The word Mach is always capitalized since it derives from a proper name, and since the Mach number is a dimensionless quantity rather than a unit of measure ...
