摘要： PROBLEM TO BE SOLVED: To provide a compact image display by achieving dynamic axis adjustment with a simple structure and a simple detection and control method for eliminating an image deterioration factor caused by dynamic variation of a beam shape of an R/G/B-color laser light source and overlap between a plurality of beams.SOLUTION: A mirror oscillating around at least one axis is driven, and a light source installed to a displacement part is driven to emit light synchronously with an oscillation period of the mirror. The position of the light source is finely adjusted by the displacement part so that a light beam is incident on the mirror plane. Behind the mirror incident plane, a plurality of photosensors detecting intensity of light are arranged. In the maximum oscillation angle condition, leak light of light beams deviating from the mirror is received by the photosensors, and a light receiving period and intensity of the light are converted into electric signals. When the light source position is adjusted so that output periods and output intensity of the respective photosensors are equalized, luminous flux is made to be incident on the mirror center.
