Abstract

Interferometric modification of the Hartmann test method has been used for observatory tests of the optics of the Danish 1.5 m telescope on La Silla. Some results of the tests and our analysing methods are presented. We use the measured wavefront aberrations to compute the point source diffraction tmage. The computing method can also be used for theoretical analysis, e. g. for investigating the effects of the mirror deflections due to the supporting system.
