A Wavefront Slope Processing Method Based on FPGA Technique

以61单元自适应光学系统中的高速实时波前处理机为例,分析了传统基于DSP的波前斜率 处理方法的优缺点,提出了一种基于FPGA技术,采用单像素控制的新型波前斜率处理方法,该方法可使得波前斜率处理机的实时性更强、体积更小,并能适用于不同子孔径布局和不同子孔径数的自适应光学系统。

With the fast-speed real-time wavefront processor in 61-element adaptive optical system as ex- ample, both its advantages and disadvantages are analyzed, a novel wavefront slope processing method with single pixel is proposed based on FPGA technique. The method will enable the wavefront slope processor to have a stronger real-time characteristics and smaller volume, and can be suitable for the adaptive optical system with different sub-aperture layouts and different sub-aperture numbers.
