Method of calculating scanning trajectory of light and optical scanning device

摘要

It is an object of the present invention to provide a method of calculating a scanning trajectory of light and a light scanning device capable of obtaining a high quality image without restricting hardware. According to a first aspect of the method of calculating a scanning trajectory of light according to the present invention, there is provided a method of calculating a scanning trajectory of light comprising the steps of detecting a resonance frequency and an attenuation coefficient of a rocking portion of an optical fiber guiding light from a light source and irradiating the object with the light, And calculating a scan trajectory of the light from the resonance frequency and the attenuation coefficient. A second aspect of the method of calculating a scanning trajectory of light according to the present invention is a method of calculating a scanning trajectory of light by using a position data detected by a scanning position detector to guide a light from a light source and irradiate the object with light, And a step of calculating an approximate function of the time variation of the phase shift of the oscillating section included in the scanning locus.
