title: High-precision methods and devices for in situ measurements of thermally induced aberrations in optical elements.
abstract: An optical system that comprises two devices for remote measurements, a broadband optical interferometer and a scanning Hartmann sensor, is described. The results of simultaneous measurements with both devices and the results of numerical modeling of sample surface heating are presented.
