Abstract

We are studying about super-resolution microscopy based on parallel scanning of multiple subdiffraction-limited spots. This paper reports on improvement of signal-to-noise ratio (SNR) of super resolution images by additional digital signal processing. More specifically, the size of the digital pinhole is changed during reconstruction. Experimental results demonstrate that the SNR can be improved by using an appropriate pinhole size.
