摘要
Disclosed herein are a Lissajous dual-axial scan component and a scan frequency generation method thereof. The Lissajous dual-axial scan component scans at a fast-axial resonant frequency and a slow-axial resonant frequency. A fast-axial bias frequency and a slow-axial bias frequency are determined according to the fast-axial resonant frequency and the slow-axial resonant frequency. Fast-axial positive integers and slow-axial positive integers are determined according to a system frequency, the fast-axial bias frequency, and the slow-axial bias frequency. An irreducible fraction is determined according to the fast-axial positive integers and the slow-axial positive integers as a ratio of the fast-axial bias frequency to the slow-axial bias frequency less than 10. A scan trace repetition frequency greater than 24 Hz is determined according to the irreducible fraction in order that the Lissajous dual-axial scan component scans according to the scan trace repetition frequency.
