ABSTRACT:
A scanning optical microscope comprises a light source, an objective lens for focusing light emitted from the light source upon an object to be observed, a light deflecting optical system provided between the light source and the objective lens and including a light deflector formed by an acousto-optic light deflector (AOD), photoelectric transducing means for detecting light from the object, and light shielding means having an elongated aperture provided between the object and the photoelectric transducing means. Light from the light source is deflected by the AOD to scan the object at a high speed, and light from the object is led to the photoelectric transducing means through the aperture of the light shielding means, without passing through the AOD, to realize confocal microscopy.
