为使采用激光光源和CCD线性阵列传感器的光学仪器设备(图1a)获得最佳性能。A/D变换器应该运行在最大可能的范围内。你可以通过延伸快闪A/D变换器的上基准,使之与CCD阵列中的最高光像素一致,就能使这个范围达到最大值。大多数快闪A/D变换器允许你控制基准电阻器阵列的末端。为了对光通路变化
Optimal performance for optical instrumentation (Figure 1a) using laser light sources and CCD linear array sensors. The A / D converter should be operated to the maximum extent possible. You can maximize this range by extending the upper reference of the flash A / D converter to match the highest light pixel in the CCD array. Most flash A / D converters allow you to control the end of the reference resistor array. In order to change the optical path
