也许等到了2022年世界杯，当我们所有人都能够在自己家的视距仪上观看全息的世界杯比赛时，EQ滤波器将被安装在设备里面。

Perhaps in 2022, when we all attend holographic games at our home stadia, EQ filters will be built in.

针对侦测系统性能低这一背景，提出一种基于粒子滤波算法的全息检测器。

Since the performance of the detection system is low, a holographic detector base on particle filtering is put forward.

可以用胶片、全息图和光栅作为滤波片。

Film, holograph and grating can be used as the filter.
