A tunable surface-emitting integrated lighting system is constructed using a combination of inorganic light-emitting diodes (LEDs) and transparent organic LEDs (OLEDs). An RB two-color LED is used to supply red and blue light emission, and a green organic LED is used to supply green light emission. Currents of the LED and OLED are tuned to produce a white color, showing different Commission Internationale d’Eclairage (CIE) chromaticity coordinates and correlated color temperatures with a wide adjustable range. Such an integration can compensate for the lack of the LED’s luminance uniformity and the transparent OLED’s luminance intensity.

对地球模拟器进行光学精密校准是保证双圆锥扫描红外地平仪单机地面性能测试的必要前提。采用两台电子经纬仪建立三维坐标实时测量系统, 实现对双圆锥扫描红外地平仪地球模拟器的精密光学校准。根据理论设计值作为参考值, 与实际测量值进行比较, 反复放样测量, 进而调整地球模拟器的冷热边界, 调校精度可使地球模拟器边界特征点坐标的定位误差控制在 0.2 mm之内。高精度位置控制保证了双圆锥扫描红外地平仪高精度的噪声等效角性能测试, 可以保证噪声等效角 (3σ)控制在 0.07°以下。
