成形空间滤波器的空间响应的方法及系统
Abstract:
本发明揭示一种空间滤波器，其包括数个在时间域中生成单独信号的光电探测器。所述单独信号随后被分割并组合以形成从空间滤波器的I通道及Q通道输出。在I及Q通道形成之前，使用一窗函数来成形所述空间滤波器的空间响应。
Abstract(English):

A spatial filter includes a number of photodetectors that generate individual signals in the time domain. The individual signals are subsequently divided and grouped to create the I and Q channels output from the spatial filter. Prior to the formation of the I and Q channels, a window function is used to shape the spatial response of the spatial filter.
