To enable the accuracy and speed of analysis and classification to be improved while maintaining an optical system.SOLUTION: An analysis method comprises: a step of forming a structured illumination pattern having a plurality of regions into which some region of light from a light source is divided, and in which light characteristics free of time changes are different, and irradiating an observation object present in a light irradiation region with illumination light having the illumination pattern while varying the relative positions of the illumination pattern and the observation object; a step of receiving, by a receive unit, at least one light signal selected from scattered light, Raman scattered light, transmitted light, fluorescence and electromagnetic waves from the observation object; a step of converting the light signal into an electric signal by the receive unit; and a step of analyzing the observation object on the basis of a time-series signal extracted on the basis of the time base of the electric signal. Information regarding the observation object is analyzed from the time-series signal without reconstructing the image of the observation object, on the basis of the result of machine learning conducted using the time-series signal pertaining to the observation object.SELECTED DRAWING: Figure 1
