Star simulator with multi-star stellar magnitude, color and temperature adjustable

Abstract

The invention provides a star simulator with multi-star stellar magnitude, color and temperature adjustable. The star simulator with multi-star stellar magnitude, color and temperature adjustable comprises an optical telecentric collimation module arranged at the front part of a star simulator, a star point position simulation module located at the middle part of the star simulator, a star point light transmission module and a star point beam coupling module which are located in the star simulator, and a star point light generation module located at the rear part of the star simulator. The star point light generation module generates a simulating light source. The star point light generation module is composed of at least two LED modules and a controlling circuit which modulates electricalsignals input from external environment and outputs to the LED modules. Each LED module provides a star point generation source for a star, and the controlling circuit individually controls the sizeof color components of each LED module. According to the star simulator with the multi-star stellar magnitude, color and temperature adjustable, by adopting the design method of modularization, the function of stellar magnitude,color and temperature adjustable on-line is achieved, the stellar magnitude,color and temperature of multi-stellar point can be simulated, and the star simulator has the advantages of high accuracy in star point position, small error in star magnitude and high simulation degree in color and temperature.

AI Technical Summary

Problems solved by technology

[0003] The traditional star simulator can only simulate the position accuracy of star points and the accuracy of angular distance between stars, but cannot simulate the magnitude and spectral type of actual star points.

Or it can only simulate the magnitude and spectral information of a single star, but cannot simulate the distribution of star points

Therefore, there is currently no spectral static star simulator in the field of simulators that can satisfy the multi-star position, multi-star level and adjustable color temperature at the same time.
