In order to realize the rapid and high precision calibration of standard scattering plate used in calibrating visibility meter, based on the calibration principle which a standard scattering plate calibrates a forward scattering visibility meter, an error analysis method for the optical system of the standard scattering plate calibration system used in a calibration visibility meter was established. The working principles of the calibration system were analyzed, and subsequently, a model of this optical system was established with a combination of the deviation arising from its optical system, fabrication and adjustment. Further, an experiment was designed to validate the model's correctness. Next, the main errors that affect the precision of the scattering plate's optical system were analyzed, for which an error propagation model was constructed. Finally, a comprehensive error analysis method for the system is proposed and a comprehensive deviation model is developed according to the analysis of the deviation of distortion, image plane position, principal point position, image plane inclination, and focal length. Each deviation is analyzed respectively, and the allowable deviation range of the deviation of distortion, image plane position, principal point position, image plane inclination, and focal length are, in order, 0.024 mm, 0.399 mm, 0.02 mm, 0.28 rad and 0.392 mm. Consequently, there is theoretical basis for precision improvement of the calibration system and the error sources analysis and compensation during calibration. © 2017, Science Press.

To solve the bottleneck caused by the fact that solar simulators are unable to simulate a solar collimation angle of 320 and an irradiance of one solar constant at the same time, we designed a new type of optical system for solar simulators. Five major design aspects of the optical system are addressed: The hybrid condenser, collimation lens, field stop, optimization of the optical integrator and the effects on the non-uniformity when the projector lens is defocused. The results show that the solar simulator described in this paper can realize a solar angle of 320 and an irradiance of one solar constant. Meanwhile, the non-uniformity is less than ±1.34% when the irradiation area has a diameter that is no more than 100 mm and in the 100-300 mm diameter range is less than ±3.8%. © 2017 Optical Society of America.

To solve the problem that the existing star simulators are only concerned with the precision of star map simulation while neglects the sky background simulation, a high-precision static star simulator was designed under a uniform background of sky. In this paper, the components and operating principles of the star simulator were elaborated emphatically, and the optimal design method was also discussed in detail for the optical system. According to simulator's optical system which was featured with big lens and high precisions, the lens cone was designed to have a fixed, tube-in-tube structure. Moreover, in order to guarantee the precision of star map simulation, the laser direct writing technology was adopted to fabricate star testers with a precision exceeding ±1 μm. Test results indicated that the star map simulation precision of the designed high-precision static star simulator with a uniform sky background is greater than 3″and the sky background uniformity is larger than 95%. Therefore, it is able to satisfy requirements of high-precision ground calibration and functional test for navigation sensors. © 2016, Science Press. All right reserved.

A scheme of star simulator spectrum simulation based on mixed light source of xenon lamp and halogen tungsten lamp for foundation was proposed. The wide spectrum light source array was composed of xenon lamp and halogen lamp. After color temperature simulation and module controlling, the light entered into the integrating sphere to provide ideal light source for star simulator, and spectral curves were stimulated at specific color temperatures of nearly 3900 K, 4800 K, 6500 K. Through the simulation of the blackbody spectrum curve of standard, the optimal transmission rate was calculated for each band filter, and the transmission rate of interval in tiny brand was combined for getting the transmission rate which satisfied the design index. The simulation results showed that, by using the proposed scheme, the small band matching simulation error would be less than 10%, with the relative area method verification matching error is within 4%, and this scheme provides an effective method for the star simulator to simulate spectral curves of the specific color temperatures.

In order to meet the requirements of multi-color temperature, high precision and wide spectrum, a large number of LED in different colors are used as internal light source for an integrating sphere. An asymmetric Gaussian function model is established to realize non-uniform spectral peak intervals. The research aims to find the desired spectral distribution of LED and the number in use through specific properties of the target spectrum to improve the obtained original fitting model.

Star simulator acts ground calibration equipment of the star sensor, It testes the related parameters and performance of the star sensor. At present, when the dynamic star simulator based on LCOS splicing is identified by the star sensor, there is a major problem which is the poor LCOS contrast. In this paper, we analysis the cause of LC OS stray light, which is the relation between the incident angle of light and contrast ratio and set up the function relationship between the angle and the irradiance of the stray light. According to this relationship, we propose a scheme that we control the incident angle. It is a popular method to use the compound parabolic concentrator (CPC), although it can control any angle what we want in theory, in fact, we usually use it above ±15° because of the length and the manufacturing cost. Then I set a telescopic system in front of the CPC, that principle is the same as the laser beam expander. We simulate the CPC with the Tracepro, it simulate the exit surface irradiance. The telescopic system should be designed by the ZEMAX because of the chromatic aberration correction. As a result, we get a collimating light source which the viewing angle is less than ±5° and the area of uniform irradiation surface is greater than 20mm×20mm. © COPYRIGHT SPIE 2015.

With continuous development of the key technologies of star sensor, the precision of star simulator have been to be further improved, for it directly affects the accuracy of star sensor laboratory calibration. For improving the accuracy level of the star simulator, a theoretical accuracy analysis model need to be proposed. According the ideal imaging model of star simulator, the theoretical accuracy analysis model can be established. Based on theoretically analyzing the theoretical accuracy analysis model we can get that the starlight emergent angle deviation is primarily affected by star position deviation, main point position deviation, focal length deviation, distortion deviation and object plane tilt deviation. Based on the above affecting factors, a comprehensive deviation model can be established. According to the model, the formula of each factors deviation model separately and the comprehensive deviation model can be summarized and concluded out. By analyzing the properties of each factors deviation model and the comprehensive deviation model formula, concluding the characteristics of each factors respectively and the weight relationship among them. According the result of analysis of the comprehensive deviation model, a reasonable designing indexes can be given by considering the star simulator optical system requirements and the precision of machining and adjustment. So, starlight emergence angle error analysis of star simulator is very significant to guide the direction of determining and demonstrating the index of star simulator, analyzing and compensating the error of star simulator for improving the accuracy of star simulator and establishing a theoretical basis for further improving the starlight angle precision of the star simulator can effectively solve the problem. © 2015 SPIE.
