Embodiment
Adaptive optics correction process system, comprises image receiver module 3, processing module 4, externally interactive module 5, DA conversion module 6.Described image receiver module receives the wavefront image data from picogram-Ha Deman Wavefront sensor 1.Processing module completes the work for the treatment of to the wavefront image data received, and its work for the treatment of comprises: wavefront center of gravity is extracted, wavefront slope calculates, flank shift gauge is calculated, control algolithm.Finally obtain the distorting lens controlled quentity controlled variable exporting to DA conversion module.DA conversion module 6 is converted into through controlled quentity controlled variable the distorting lens 7 that analog drive signal exports to its exterior distortion.Whole process is repeatedly run under certain frequency, completes the self-adaptation school to optical imagery, and computing machine 2 is by bus and external interactive module 5 communication, and external interactive module 5 obtains corresponding parameter and control command by computing machine.
The present invention is except DA transforms, and all the other work complete primarily of FPGA.Its groundwork has: image prestores; Wavefront pipeline processes; Communication and control.
Image prestores and has IP kernel and the logic composition of FIFO function primarily of FPGA inside.Object stores the image captured by picogram-Ha Deman Wavefront sensor, for increasing operation rate, calls the IP kernel of 2 FIFO functions here with table tennis algorithm.When a FIFO district is when storing view data, the data in the 2nd FIFO district flow to wavefront pipeline processes district and carry out computing.Otherwise when the 2nd FIFO district is when storing view data, then the data in a FIFO district flow to wavefront pipeline processes district and carry out computing.
Wavefront pipeline processes mainly completes the computing relevant with self-adaptation, and they comprise: wavefront center of gravity is extracted, wavefront slope calculates, flank shift gauge is calculated, control algolithm.It all completes in FPGA.
