Abstract
Disclosed are a device and method for measuring fluorescence signal in multi-illumination mode and use of the method. An excitation light is modulated on an illumination excitation light path, to generates excitation illumination patterns at different phases on a sample after passing through an objective lens; a high-speed switching device is arranged on a fluorescence collection light path to switch the position of a fluorescence image of the sample on a target plane of a photoelectric sensor, and a plurality of sub-images can be simultaneously obtained after one exposure through synchronous operation of multi-illumination excitation light paths and fluorescence imaging light paths, which correspond to fluorescence signals in a plurality of illumination modes.
