Abstract: A scanning observation apparatus (10) deflects illumination light with an actuator (25) through an illumination optical system (26) to scan an object (32), subjects light from the object (32) to photoelectric conversion with an optical detector (44), performs processing with an image processor (46), and displays an image of the object (32) on a display (60). A memory (35) stores information on optical characteristics related to chromatic aberration of magnification of the illumination optical system (26) relative to light of predetermined colors. A scanning pattern calculator (45) calculates a scanning pattern, on the object (32), of light of each color using the information. Using the scanning pattern, the image processor (46) calibrates a plot position yielded by a photoelectric conversion signal from the optical detector (44) for light of each color and generates an image of the object (32), thereby more easily correcting the chromatic aberration of magnification.

Abstract: An optical fiber is vibrated at an emitting end part by a scanning part, and light is irradiated from an emitting end face of the optical fiber onto an object to scan the object. The scanning part includes a pair of first direction coils facing each other in a first direction across the emitting end part, and a permanent magnet installed as penetrating the emitting end part. The permanent magnet is magnetized in the axial direction of the emitting end part. The scanning part drives, by supplying power to the first direction coils, the emitting end part to vibrate in the first direction in the second or higher-order resonance mode, forming nodes of the vibration within the permanent magnet. When in a state of non-vibration in the first direction, a relative distance between the permanent magnet and the first direction coils is smaller than that in other directions.
