Abstract: An instrument for the instantaneous measurement of the chromaticity of time variant spectral sources including a plurality of narrow band sensors or transducers that in combination encompass the visible spectrum. Each consists of an interference filter and a linear photovoltaic cell whose three output voltages have been ''''optimum multiplied'''' for the three tristimulus functions through a voltage divider network. The corresponding individual outputs of the sensors are added by a summing feedback amplifier to provide a voltage output proportional to the tristimulus values. These proportional outputs are then summed by a unity gain summing amplifier whose output in turn is applied to one input of a pair of ratio recorders. The other ratio recorder inputs each receive one of the proportional outputs. Each ratio recorder inputs each receive one of the proportional outputs. Each ratio recorder output, therefore, is one of the normalized chromaticity coordinates. The output coordinate values (x and y) are simultaneously fed into a chart recorder to derive a plot of the chromaticity coordinates vs. time. The invention described herein may be manufactured, used and licensed by or for the Government for governmental purposes without the payment to us of any royalty thereon.

Abstract translation: 用于瞬时测量时变光谱源的色度的仪器，包括组合包含可见光谱的多个窄带传感器或换能器。 每个都包括一个干涉滤波器和一个线性光伏电池，其三个输出电压通过分压网络对三个三刺激函数“最佳相乘”。 传感器的相应的单独输出由加法反馈放大器相加以提供与三刺激值成比例的电压输出。 然后，这些比例输出由单位增益求和放大器求和，该输出反过来被施加到一对比率记录器的一个输入端。 其他比率记录器输入每个接收一个比例输出。 每个比率记录器输入每个接收一个比例输出。 因此，每个比率记录器输出是归一化色度坐标之一。 输出坐标值（x和y）同时输入图表记录器，以得出色度坐标与时间的关系图。
