I have been looking into making an interferometer for testing the shape of a telescope mirror. This link describes an amateur version: http://www.ceravolo.com/Interferometry.pdf
A very accurate sphere (amateur made, using Foucault tester) is used as a standard to compare against the mirror being tested. I am wondering if a version of this could be used for testing machine axis accuracy using two accurate flats, one on the axis table, one stationary with the test rig? Flats can be difficult to make, but it is possible. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
