研究了基于细菌视紫红质(bR)膜的新事物滤波器的非均匀输入图像对输出图像特性的影响.与具有均匀光强分布的输入图像相比,在正弦分布的输入图像情况下,输出图像的光强分布不再呈现单调变化,而是出现两个峰值,其中间有较小的光强.bR膜的M态寿命和物体运动速度对输出图像上蓝光光强的分布有一定影响.M态寿命越大,透过的蓝光光强越小,减小的幅度是随着M态寿命的增加而减小,当M态寿命τ>50s时,减小的幅度几乎为零.在相同的入射光情况下,对于输出图像的相同位置,输入图像的运动速度越大,其输出的蓝光光强越大.
The effect of the non-uniform input image based on the bacteriorhodopsin (bR) film filter on the output image characteristics is investigated. Compared with the input image with uniform light intensity distribution, in the case of sinusoidal input image, the output The light intensity distribution of the image no longer shows a monotonous change, but appears two peaks with a smaller light intensity among them. The M state lifetime and the object moving speed of the bR film have an influence on the distribution of the light intensity of the blue light on the output image. The larger the M-state lifetime, the smaller the intensity of the transmitted blue light, and the decreasing extent decreases with the increase of the M-state lifetime. When the M state lifetime τ> 50s, the amplitude of the decrease is almost zero. Of the incident light case, for the same position of the output image, the greater the input image motion speed, the greater its output blue light intensity.
