电荷耦合器件(CHARGE-COUPLEODEVICES简称CCD)是在1969年发明的。由于它具有广泛的应用价值,因此发展得非常迅速。近年来,它已开始应用于摄像、图像分析、存储装置、自动检测等领域,在国内近几年来,CCD器件在自动检测中也崭露头角。一、CCD器件的应用特点自动检测过程中经常要求控制器发出一个要求检测的信号,检测装置就对被测零件检测一次,输出结果。当没有要求检测信号,检测装置就不工作。但是,CCD器件却必须在一定频率下连续工作。这就是说,不管是否有要求检测信号,CCD器件总是不断地在检测,发出脉冲,反复
Charge-coupled devices (CHARGE-COUPLEODEVICES referred to as CCD) was invented in 1969. Because of its wide range of application value, it has developed very rapidly. In recent years, it has been used in the field of camera, image analysis, storage device, automatic detection and other fields. In recent years, CCD devices have also come out in the automatic detection. First, the application characteristics of CCD devices Automatic detection process often requires the controller to issue a signal required to detect the test device on the measured parts of the test, the output results. When no test signal is required, the test device will not operate. However, CCD devices must work continuously at a certain frequency. This means that regardless of whether the detection signal is required, the CCD device constantly detects, pulses, and repeats
