Abstract

The invention relates to a standard starlight simulator and a stray light PST (point source transmittance) optical detection system containing the same. The standard starlight simulator comprises a light source, an iris diaphragm, a dodging instrument, a star point plate and a collimation system; the iris diaphragm is arranged on the incident optical path of the light source; the dodging instrument is arranged on the output optical path of the iris diaphragm; the star point plate is arranged above the dodging instrument; and the collimation system is arranged on the output optical path of the star point plate. The invention provides the standard starlight simulator which can greatly enlarge the range of the simulated stellar magnitude and realize accurate measuring and calibrating under pianissimo light environment and has high measurement accuracy, and the stray light PST (point source transmittance) optical detection system containing the simulator.

Description

technical field [0001] The invention relates to a standard starlight simulator and a stray light PST optical detection system containing the simulator. Background technique [0002] The starlight simulator is a standard source of measurement benchmarks, mainly for the purpose of establishing a standard magnitude and luminosity. As a ground calibration device, the star simulator simulates the weak star illumination, star angle diameter and spectral characteristics, and is used to test and calibrate the sensitivity of stars, satellite detectors and star sensors to space targets of different magnitudes and spectral characteristics. It meets the needs of ground simulation tests of starlight detectors and star sensors. At present, the star simulator has become a key instrument for ground calibration tests of starlight detectors and star sensors. [0003] As the requirements for the detection capability and accuracy of starlight detectors are getting higher and higher, this will...
