Abstract
A scanning-type image acquisition device includes: drivers that respectively vibrate in an x direction and a y direction that are perpendicular to a longitudinal axis of an optical fiber that guides illumination light from a light source and cause a tip of the optical fiber to be spirally scanned on a subject; a drive-signal generating circuit that generates drive signals for driving the drive units; an adjustment section that adjusts the drive signals generated by the drive-signal generating circuit and generates position reference data; a photodetector that detects scattered light of the illumination light at each scanning position of an illumination light spot on the subject due to the drivers; and an image generating circuit that generates an image by arranging intensity values of the scattered light detected by the photodetector in pixels in accordance with the position reference data output from the adjustment section.
