Each of its pixels is sensitive to specific incident angles and supplies a component of the mathematical operation called the FourierTransform to produce an image about 20 pixels across.
That's part of what makes Fourier wonderful. "Nonetheless, for some signal-processing applications, banded matrices could prove more efficient than the Fouriertransform."
那是傅里叶变换美妙的部分，但对于某些信号处理应用来说，带状矩阵可以比傅里叶变换更加高效。
