convolution

对正弦波进行FFT（快速傅立叶变换）得到幅频谱图，均方根谱图，功率谱图，对数谱图，并进行IFFT恢复出正弦波。(FFT and IFFT)

We propose a novel fluorescence emission difference microscopy (FED) system based on focusing cy- lindrical vector beams. In conventional FED, a Gaussian beam and a 0–2 π vortex phase plate are used to generate solid and hollow spots. We focus radially polarized and azimuthally polarized cylindrical vector beams to obtain an expanded solid spot and a shrunken hollow spot, taking advantage of the optical properties of cylindrical vector beams to improve the conventional FED performance. Our novel method enhances FED performance
