Abstract
The present disclosure relates to a method of determining and maintaining a scanning condition for optimal Lissajous scanning. According to the present disclosure, the method includes selecting a frequency combination and a mapping time delay difference, when minimum scanning density according to the mapping time delay difference in the frequency combination within a preset frequency range for two axes is maximum, as an optimal scanning condition, and maintaining optimal scanning by applying a modulated drive phase offset to compensate for a deviation between an actual time delay difference and an optimal time delay difference selected as the optimal scanning condition due to a delay index adjusted according to an actual phase change. As described above, according to the present disclosure, a frequency combination may be more flexibly selected from a frequency combination having a decimal point in implementing Lissajous scanning. In addition, an optimal scanning condition may be determined, and scanning density may be continuously maintained greater than or equal to a certain level.
