Abstract: A method and a controller for operating an array of variable optical retarders are disclosed. Neighboring pixels of the array of variable optical retarders are driven with disordered temporal bit sequences. An optical beam illuminating the pixels tends to integrate time-domain modulation caused by individual pixels driven in a non-coordinated or disordered fashion, which reduces the overall time-domain modulation amplitude of the optical beam.

Abstract translation: 公开了一种用于操作可变光学延迟器阵列的方法和控制器。 可变光学延迟器阵列的相邻像素由无序的时间位序列驱动。 照射像素的光束倾向于集成由以非协调或无序方式驱动的各个像素引起的时域调制，这降低了光束的总体时域调制幅度。
