三、CCD图像传感器的应用 CCD图像传感器已经在国外得到广泛的应用,但是目前在国内还没有形成商品化。下面介绍一些实例,有助于推动CCD图像传感器应用研究的开展。 (一)长度测量用CCD图像传感器可以进行长度的非接触精密测量。由于测量的迅速和数据处理方便,因此可用于自动生产线的监控上。图7是一个钢管长度监测系统的实例。在被测钢管(1)的背后放两个荧光灯(2)、(3)作为光源,两荧光灯之间的距离LT已知。荧光灯未被钢管遮住的部分L_1和L_2经两个透镜分别聚焦在两个COD传感器上。根据传感器输出信号的脉冲数,光敏元的尺寸以及透镜光学系统的放大倍数即可求得L_1和L_2.最后由
Third, the application of CCD image sensor CCD image sensor has been widely used abroad, but at present there is no commercialization in China. Here are some examples to help promote the application of CCD image sensor research. (A) Length Measurement CCD image sensor can be non-contact length measurement precision. Due to the rapid measurement and data processing convenience, it can be used for automatic production line monitoring. Figure 7 is an example of a pipe length monitoring system. Two fluorescent lamps (2) and (3) are placed behind the steel pipe (1) as a light source, and the distance LT between the two fluorescent lamps is known. The parts L_1 and L_2 whose fluorescent tubes are not covered by steel tubes are respectively focused on two COD sensors by two lenses. According to the sensor output signal pulse number, the size of the photosensitive element and the magnification of the lens optical system can be obtained L_1 and L_2 Finally by
