目标移动情况下SSPA输出信号的分析

自扫描光电二极管阵列图像传感器用于物体测量时，物体的外型尺寸反映在图像传感器的输出信号里，对物体的识别测量以及指标的提高很大程度上取决于对视频输出信号的特征的提取。基于对自扫描光电二极管阵列图像传感器输出信号的分析的要求，文中根据光电二极管光电转换原理，从理论上分析了自扫描光电二极管线阵列图像传感器拍摄运动目标识别视频输出信号的数学模型，分析了用比较法处理视频输出信号时可能出现的误差大小，理论分析结果与传感器输出的实际波形相吻合。

Video Signals of a Self Scanned Photodiode Array Image Sensor

When self-scanned photodiode array image sensors are applied in object measurements, the outer sizes of the object are included in the video signal of image sensors. The identification and measurement of the object ,and the enhancement of the performance is depended on the symbol extraction of the video output signals. Based on the working principles of self-scanned photodiode array image sensors, the mathematical models of image sensor's video signals are established when the moving object is captured. The comparative method and the measurement error are researched. The results of this paper provide a theoretic basis for the research of video signals processing.
