Study of spectral responsivity testing technologyfor photocathodes of image intensifiers

  • 摘要: 针对像增强器不仅具有光电成像而且具有光谱转换的特殊性,分析了像增强器的工作原理。提出了以腔体热释电探测器为基准探测器测量像增强器(裸管)光阴极光谱响应的新方法,给出了像增强器光阴极光谱响应的测量原理。通过用辐射标准低温辐射计和辐射传递标准陷阱探测器对硅光电二极管 632.8nm 处的绝对光谱响应度定标,实现了对像增强器光阴极全波段绝对光谱响应度的标定。设计的高精度、宽光谱的像增强器光阴极光谱响应测量装置有益于像增强器光阴极的研制与制作。

     

    Abstract: The working principle of the image intensifier is analyzed since it has not only the special property of optoelectronic imaging but also the characteristic of spectral conversion. A new method, which takes a cavity pyroelectric detector as a reference detector to measure the spectral responsivity of photocathodes in image intensifiers, is proposed. The measurement principle of the photocathode spectral responsivity for image intensifiers is described. The calibration of allwave absolute spectral responsivity of photocathodes in image intensifiers was realized by means of the calibration of the absolute spectral responsivity at 632.8nm for a silicon photocathode by using the cryogenic radiometer of the radiation standard and the trap detector of radiation transfer standard. The highprecision and broadband instrument designed for measuring the spectral responsivity of photocathodes in image intensifiers is of benefit to the development and fabrication of photocathodes in image intensifiers.
