美国EG＆G公司生产的新型EG＆GLD2040型数字式线扫描相机的扫描速度和精度都高于普通的CCD阵列相机。这种新型扫描相机采用了独特的双通道光电二极管图像传感器,它可提高相机的光谱响应,并且保持低噪声特性。相机内装有一个微处理器,通过RS—232接口可存取信息,因此,可以直接控制增益、偏差、扫描速度和曝光时间,在工厂的环境,用来高度扫描、分类、监视和测量。该相机系统有7μm像元尺寸空间分辨率为4096像元。传感器的双线结构允许通
The new EG & GLD2040 digital line scan camera produced by EG & G in the United States is faster in scanning speed and accuracy than a normal CCD array camera. The new scanning camera features a unique dual-channel photodiode image sensor that increases the spectral response of the camera while maintaining low noise. The camera has a microprocessor built in to access information via the RS-232 interface, thereby directly controlling gain, skew, scan speed and exposure time in the factory environment for high-scan, sort, monitor and measure. The camera system has a 7μm pixel size with a spatial resolution of 4096 pixels. Two-wire sensor structure allows the pass
