A new Hartmann test method and principle based measurement of radial wavefront slop are presented,and structure of an 800 mm aperture Hartmann test system based on this method is built. Test on a 700 mm aperture telescope using this system is performed,and the testing results show that it can be used to test the optical quality of large telescope and aspheric mirror indoor without using large flat mirror.
