使用单像素检测器通过从正交时变空间线调制光栅时间复用空间频率投影来获取二维（2D）图像。独特的时间频率被应用于2D空间中的每个点，将频率的连续扩展应用于一维，并且将偏移频率应用于正交维度中的每条线。然后可以从单个像素的电子光谱中恢复对象对比度信息，并通过简单的处理将其重新形成空间图像。
Two-dimensional (2D) images are taken using a single-pixel detector by temporally multiplexing spatial frequency projections from orthogonal, time varying spatial line modulation gratings. Unique temporal frequencies are applied to each point in 2D space, applying a continuous spread of frequencies to one dimension, and an offset frequency applied to each line in the orthogonal dimension. The object contrast information can then be recovered from the electronic spectrum of the single pixel, and through simple processing be reformed into a spatial image.
