title = "Simultaneous null test of primary mirror and tertiary mirror in off-axis three-mirror optical system",
abstract = "The null test of off-axis mirror plays a very important role in off-axis three mirror optical system design. The detection device depends on either complex detection optical system designs or high-precision null lens design. Both can only test one off-axis mirror and are not non-universal. In order to increase the detection efficiency, we innovatively propose a simultaneous null test method of primary mirror and three mirror in off-axis three mirror optical system. The simultaneous null test device is composed of a liquid zoom null lens. Simulation results show that the residual wavefront errors of testing a primary mirror and tertiary mirror are approximately 0.001 peak-to-valley (PV), and 0.003 (PV), respectively.",
