According to some specific problems of conventional star simulator including the less simulation parameters, low accuracy and big difficulty of star simulation technology, by creatively introducing the μLED luminous technology into the design of star simulator, a development scheme of novel star simulator based on the μLED luminous technology was proposed. Combining with design results of collimating optical system, the overall mechanical structure of star simulator was designed in detail, to ensure that the designed simulator having characteristics of the largest possible weakening of temperature change, vibration and other external factors in the simulation environment. Control technology of star position accuracy, star brightness, star roundness, emitting uniformity of star light was researched and analyzed. Analysis and test results show that the designed star simulator owing the properties of angular distance precision between stars less than 3″, a variety simulation of 5 continuous magnitudes, at the same time to meet multi-parameter simulation requirement about the star roundness, luminous uniformity and luminescence spectra. The proposed design method can provide a feasible technical solution for the development of higher level of star simulator.
