Ground testing system for detecting optical performance of space remote sensing spectrometer
摘要
Abstract
For detecting optical performance of space remote sensing spectrometer, the ground testing system is designed and implemented.The system consists of hardware and control software.The hardware consists of light source, mechanical motion subsystem, signal acquisition subsystem and computer.The control software is implemented in the Windows environment with Labview.The subdivision driving and the method of computing the number of steps considering error term are used to reduce the accumulation of errors in motor control.Scanning mechanism is controlled by specified wavelength scan or continuous wavelength scan, and the spectral curve is displayed in real-time.The SNR is calculated automatically, the area of interesting is fitted based on Gaussian fitting with generalized least squares, the bandwidth is read automatically.The experiment results show that the system can achieve detecting optical performance of space remote sensing spectrometer in full wave band automatically.The wavelength accuracy is better than ± 0.05 nm, and the repeatability is better than 0.01 nm, the calculation of SNR is completed within 1 s.The spectral bandwidth is less than 1 nm.The system accomplishes the requirements, increases efficiency and lays the foundation for the development of aerospace load.关键词
