Abstract:
1. A scanning microscope comprising: a light source; an optical system that irradiates light from the light source onto a sample while two-dimensionally scanning the light, and collects light from the sample; a photo-detector that receives the light from the sample which has been collected by the optical system, and converts the light thus received into a brightness signal; an integrating circuit that integrates the brightness signal from the photo-detector for each pixel; and an image forming circuit that forms an image of the sample based upon the brightness signal of each pixel integrated by the integrating circuit, wherein the integrating circuit includes a plurality of integrators for integrating the brightness signal from the photo-detector and an adder for adding output signals from the plurality of integrators, and integrates the brightness signal while sequentially switching the plurality of integrators for each of a plurality of periods obtained by dividing a period corresponding to a pixel.
