Method of photocatalytic redox reaction based on structured light illumination and device thereof

A device of photocatalytic redox reaction based on structured light illumination, comprising:

• a computer module, being configured to send control instructions to a structured light generation module and an image acquisition module, to control generations of a structured illumination field and a total internal reflection illumination field, and acquisition of images of single-molecule fluorescence;
• the structured light generation module, comprising a plurality of lasers, an acousto-optic tunable filter (AOTF) and a spatial light modulator (SLM), and being configured to control the plurality of lasers, the AOTF and the SLM according to the control instructions sent by the computer module, to generate and regulate the structured illumination field for exciting a photocatalytic redox reaction, and generate and regulate the total internal reflection illumination field for exciting the single-molecule fluorescence;
• and
• the image acquisition module, being configured to acquire images of fluorescence signals in a process of the photocatalytic redox reaction.
