摘　　要：为实现激光光斑图像的高速采集,利用DS-4004 HC图像采集卡配置CCD探测器,并且通过动态地分配和控制计算机内存的空间,对其添加软件触发新功能,开发了图像采集系统,给出了在VC++6.0环境下利用图像采集卡进行用户二次开发的主要流程和关键技术。实验表明,该系统可实现单发或连续的高速采集激光光斑图像,响应时间短,可靠性高。By using the image acquisition card DS- 4004HC and CCD detector as the image acquisition system and dynamically allocating and controlling of computer memory heap space to add software trigger function for high speed laser facula image acqaisition,the main flow chart and key techniques based on VC＋＋ 6.0 are redeveloped. The experiments demonstrate the advantages of the high speed image acquisition with short response time and high reliability.
