小角激光散射是一种有效的测量高聚物球晶半径的方法。传统SALS图像采集方法复杂、不易调节, 图像质量不够理想。数字成像技术提供了很好的替代手段,但目前主要采用CCD摄像机直接采集散射图像,它的成 本较高,操作和处理不够灵活。利用CMOS成像技术采集散射光在毛玻璃上所成的像,能使图像采集的硬件成 本大为降低而且操作方便,简化了SALS图像数据采集和后期处理。

Small angle laser scattering(SALS) is an effective measurement of the polymers spherulite radius. The conventional measurement of SALS image collection is complicated and difficult to adjust. The quality of the image is not ideal. Digital imaging technology is a good substitution, but now the main measurement is using CCD camera to collect the image directly of which the cost is high and the operation and management are not flexible. Take the advantage of CMOS imaging technology, digital CMOS camera can receive the image which is present on the ground glass by scattering light. This measurement not only reduces the cost of the hardware but also makes the operation facilitated and simplifies the SALS image collection and process.
