CCD系统线性动态范围的标定
Calibration of linear dynamic range for CCD system
-
摘要: 提出了一种标定CCD图像采集系统动态范围的实用方法。利用尖劈形成一列光强逐级衰减的标定光源,结合插值法给出CAS-512A CCD系统的线性动态范围。可用于强激光领域中CAS-512A CCD图像采集系统的实用线性动态范围的标定。Abstract: With many advantages, scientific grade CCD camera has been applied to diagnose the quality of laser beam in the field of highpower solid laser. Linear dynamic range is one of the most important characteristics. A new method calibrating the dynamic range for CAS-512A CCD system with optical wedge is reported.
