In order to design a compact star simulator based on multiple LEDs, optical fibers, an integral sphere and tiny collimated optical systems are employed in the system. Firstly the system configuration block diagram of the star simulator is given in this paper. Then the luminous flux calculation of LED is calculated based on the optical system. Finally the principle of PWM control of LED is illustrated. The analysis shows that the simulated precision of star magnitude can achieve ±0.1m.
