本文研究的是以线阵CCD接收器为基础的多通道光学探测器的计量学特性。给出绝对灵敏度、变频跨导、噪声、动态范围和非线性的测量方法和结果。讨论了系统误差的来源及其消除方法。描述了CCD接收器12007所用的图像记录系统,为此测量了:动态范围(1600),绝对灵敏度(400光子/像元),变频跨导(200光子/读数),灵敏度的不均匀性(0.5％),非线性系数(1.07)。系统的数学保证使得能够校正CCD的畸变。校正后的误差对于大信号为0.15％。
This article investigates the metrological properties of multichannel optical detectors based on linear CCD receivers. The measurement methods and results of absolute sensitivity, transconductance, noise, dynamic range and nonlinearity are given. The source of system error and its elimination method are discussed. Describes the image recording system used by the CCD receiver 12007, for which measurements of dynamic range (1600), absolute sensitivity (400 photons / pixel), transconductance (200 photons / reading), non-uniformity of sensitivity %), Non-linear coefficient (1.07). The system’s mathematical guarantees make it possible to correct CCD distortion. The corrected error is 0.15% for large signals.
