摘要：
A fundus imaging apparatus includes a scanning optical system, a control circuit, and an image forming unit. The scanning optical system scans a fundus of a subjects eye with light from a light source, and receives return light from the fundus by a light receiver. The control circuit controls the scanning optical system such that a scanning locus is formed by the light in the fundus. The image forming unit forms an image of the fundus based on a light receiving signal from the light receiver and a position of the scanning locus. The control circuit is capable of performing an alignment mode, in which the control circuit controls the scanning optical system to project an alignment indicator for aligning the scanning optical system with the subjects eye on the fundus based on the light from the light source.
