摘要
为有效控制成像光谱仪中心波的测量射线、实现对地面定标角度的灵活转换,本研究设计了成像光谱仪视场中心波长定标角度的自动控制方法。通过选择定标光源的方式,搭建波长定标装置,再借助处于既定位置处的测试光源,完成对中心波光谱的定标处理。分别计算中心波测量射线的水平方向与垂直方向转角,利用已生成的角度控制程序实现对定标角度的自动化控制。实验结果表明:应用本文方法后,地面定标角度的实际变动范围始终处于30°至165°之间,可实现对成像光谱仪中心波测量射线的有效控制。
In order to effectively control the measured rays of the center wave of the imaging spectrometer and realize the flexible conversion of the ground calibration angle,an automatic control method for the calibration angle of the center wavelength of the imaging spectrometer is designed in this study.By selecting the way of calibration light source,the wavelength calibration device is set up,and then the calibration process of the central wave spectrum is completed with the help of the test light source at a given location.The horizontal and vertical angles of the measured ray are calculated respectively,and the automatic control of the calibration Angle is realized by using the generated angle control program.The experimental results show that the actual variation range of the calibration angle of the ground is always between 30°and 165°after the application of this method,and the effective control of the measured ray of the center wave of the imaging spectrometer can be realized.
