本文介绍的测光头是为统一全国荧光显示管亮度的测量装置而设计制作的测光头。采用标准亮度源进行标定,并可用小光源对系统进行监视和比较校正。这些装置和方法适用于低照度显示面(如电子束器件、场致发光板等)的亮度测量。本文分析了亮度(β)的误差。除了测量方法和测量的误差外,误差主要是由标定(a)和测量装置等因素所引起。这些因素在设计测光头时应加以考虑。本文针对测光头应满足的条件对测光头选用的光电元件、测光头套筒的长短和大小、发光面的方向等进行了设计分析,并加以验证,估计了误差,从而决定出测光头的结构。介绍了供全国标定和测量使用的可变距的测光头,以及适用于不同管型的可变角度的测光头的设计和制作。
This article describes the metering head is to unify the national fluorescent display tube brightness measuring device designed and manufactured head. Standard brightness source calibration, and the system can be used to monitor small light and compare the correction. These devices and methods are suitable for brightness measurement of low-illuminance display surfaces such as electron beam devices, electroluminescent panels, and the like. This paper analyzes the brightness (β) error. In addition to the measurement method and measurement error, the error is mainly caused by the calibration (a) and the measuring device and other factors. These factors should be taken into account when designing the head. In this paper, we should design and analyze the optoelectronic components, the length and size of the optical pickup sleeve, the direction of the light emitting surface and so on, which should meet the requirements of the optical pickup, and verify and estimate the error so as to determine the measurement Bald structure. The variable pitch heads for calibration and measurement in the country are introduced, as well as the design and manufacture of variable angle heads for different tube types.
