需要处理的数据量大，要求处理的速度快，是应用于Ｈ－Ｓ波前传感器的自适应光学波前信号处理机的主要特点。本文完成了利用ＴＭＳ３２０Ｃ２５作为处理器，应用于２１单元Ｈ－Ｓ波前传感器的实时波前信号处理的研制。该系统完成对Ｈ－Ｓ波前传感器输出的高帧频图象信号的采集、处理，并计算出波前校正所需的控制信号，处理速度不低于２５０帧／秒。系统有以下特点：①系统有两块图象采集存贮区，一块进行采集时，另一块进行处理，这样可以提高速度；②为了实验中光路调试的方便，系统具有实时图象显示功能；③在Ｃ２５所带存贮区较多的情况下，通过周密的逻辑设计，保证了系统在无等待状态下运行；④在软件设计上，充分考虑所处理数据的取值范围及计算结果的精度要求，并充分利用Ｃ２５的特点，以尽可能提高速度；⑤系统紧凑，可插在微机扩展槽上 The large amount of data that needs to be processed, requiring fast processing, is a key feature of adaptive optical wavefront signal processors that are used in H-S wavefront sensors. This paper has completed the development of real-time wavefront signal processing using TMS320C25 as a processor and 21-element H-S wavefront sensor. The system completes the collection and processing of the high frame rate image signal output from the H-S wavefront sensor and calculates the control signal required for wavefront correction at a speed of not less than 250 frames / second. The system has the following characteristics: ① The system has two image acquisition and storage areas, one for collection, the other for processing, so you can speed up; ② In order to facilitate the optical path debugging in the experiment, the system has real-time image display; ③ In the case of C25 with more storage area, through careful logic design to ensure that the system runs without waiting state; ④ in the software design, take full account of the range of data processed and the accuracy of the calculation results , And take full advantage of the characteristics of C25, in order to maximize the speed; ⑤ compact system can be inserted in the computer expansion slot
