| 摘 要： | 传统的彩色亮度计一般采用光探测器结合马达旋转三色滤色片构成色度传感器;本文提出的分镜式亮度传感光学系统,采用了分镜式三色分离成像结构,使由红绿蓝滤光片组获得的三色信号和探测器直接组合形成色度传感器,由于减少了运动部件,因此改善了仪器可靠性、稳定性,降低了系统功耗。

| Abstract: | In traditional luminance colorimeter, the tricolor sensor is usually combined of the Si photodetector and X(λ)Y(λ)Z(λ) filters which are rotated by a motor. A novel luminance detecting optical system with separated lens structure is presented, which combines 3 sets of lens and 3 photodetectors with X(λ) Y(λ)Z(λ) filters respectively, hence the chromatic signal can be obtained directly. Since the moving unit of motor has been erased, the reliability and stability will be impreved mean while the power consumption will lowered. |
