The effect of detector array size on resolution and signal collection efficiency of image scanning microscopy based on pixel reassignment is studied. It is shown how the method can also be employed if there is a Stokes shift in fluorescence emission wavelength. With no Stokes shift, the width of the point spread function can be sharpened by a factor of 1.53, and its peak intensity increased by a factor of 1.84.
研究了基于像素再分配的图像扫描显微镜的探测器阵列大小对分辨率和信号采集效率的影响。还展示了如果荧光发射波长存在斯托克斯位移，该方法如何也能被采用。在没有斯托克斯位移的情况下，可以将点扩散函数的宽度锐化 1.53 倍，其峰值强度增加 1.84 倍。
