Enhancement of weak signals by dynamic stochastic resonance in dark-field microscopy

Abstract Enhancing weak signal acquisition is pivotal for bolstering analysis and detection capabilities. Herein a dynamic stochastic resonance (DSR) algorithm for weak signal amplification is presented, which was identified to significantly improve the imaging visibility of dark-field microscopy (DFM) nanoparticle under low illumination conditions. By combining with composite filed microscopy (CFM) further, DSR displays much more effectively signal amplification, showing high promise for detection purpose.
